Purple Daze 1, Various Purply Names

Occasionally, I kick around purple colors in my head. I've been dazed about them more than other colors pertaining to elementary school crayon colors, primary/secondary tempra colors from art class, and visible light colors. Purple seems a more dominant color name than violet, which Crayola uses, but with a nod to purple. "What were the original eight (8) colors in the 1903 box of Crayola Crayons?" lists the color as "violet (purple)".

My pixstrip shows purply clothing items (some with only smaller purply bits) and corresponding color snippets with lighter background. I wistfully thought about a couple of purply items I donated in the distant past.

Eye See Violet and Purple 

Hmmm, so what's the deal about the dodgy term "violet (purple)"? Are they the same color? Some resources explain:

"Difference between ‘violet’ and ‘purple’" (purple/violet contrast image at the author's article)

purple looks more “reddish” than violet … Purple is formed by mixing red and blue at a ratio close to 1:1, whereas violet is perceived by your eyes as containing more blue than red. … no spectral colour activates the “blue” path and the “red” path at the ratio of 1:1 without also stimulating the “green” path. In other words purple is not a spectral colour.

Purple is a mixture of red (which is at the opposite side of the spectrum than violet) and blue (which is relatively far from violet), so it is, in terms of wavelengths, a completely different colour.

"Violet and Purple Aren't The Same Thing"

When you see brown, you're seeing a mixture of light wavelengths that activate different cones in varying ratios to produce a color your brain finally interprets as brown.

Violet activates the blue and red cones—the blue cones a lot, the red cones a little less. Purple, on the other hand, hits your eyes in the same way our brown example did above. It's a combination of the spectral colors blue and red. Rather than activating blue and red cones in a given ratio, purple combines the cone ratio for blue with the cone ratio for red to come up with an entirely new color.

"Purple Color Meaning – The Color Purple"

The difference between violet and purple is that violet is displayed in the visible light spectrum, while purple is simply a mixture of red and blue. Violet vibrations are the highest in the visible spectrum. … violet is not quite as intense as purple

"Primary colors: The truth about purple"

Purple is a mixture of colors, like white. If you mix blue light and red light, your eye will see purple, but in reality, it’s just a mix of blue and red. … Scientifically, purple is not a color because there is no beam of pure light that looks purple. There is no light wavelength that corresponds to purple.

"The Meanings of Purple" is loaded with information; however, the absence of "violet" is somewhat suspicious. The article does link to a probably more technically correct explanation regarding visible wavelength, which is violet.

Purple is the most powerful visible wavelength of electromagnetic energy. It’s just a few steps away from x-rays and gamma rays. …

Variations of purple convey different meanings: Light purples are light-hearted, floral, and romantic. The dark shades are more intellectual and dignified. …

The earliest purple dyes date back to about 1900 B.C. It took some 12,000 shellfish to extract 1.5 grams of the pure dye - barely enough for dying a single garment the size of the Roman toga.

Loads of Various Purply Colors

Besides violet and purple having dazed me, I've also been befuddled by other purply terms, which I hesitate to label such-color items. Many of them pertain to flowers or fruit.

Lilac and lavender have confused me lots over the years. "Lavender vs. Lilac: What's the Difference?" contrasts these purply colors with pictures, a table, and descriptions. I thought about the song "Lavender Blue". Coincidentally, I ran across another similarly worded song that also mentions "lavender blue", "lavender green", "dilly, dilly", "king", and "queen".

Grape and plum are a couple of foods with purply colors. For grape flavors, such as ades, jellies, and jams, seems all grape colors are purple, excepting wines and juices ("white grape" somethings).

The oddest purply color I've encountered is "aubergine", associated with another food—eggplant. "Why Is It Called an Eggplant?" explains the color as well as the eggplant name itself.

There is actually a color — aubergine — that resembles the purple of the eggplant.

A long, gourd-shaped, purple fruit is what most people think of when they hear the word “eggplant." … way back in the 1700s, early European versions of eggplant were smaller and yellow or white. They looked a bit like goose or hen's eggs, which led to the name “eggplant."

I mentioned "mauve" earlier. Oddly, Merriam-Webster's entry for "mauve" shows differing definitions that seem non-committal:

a : a moderate purple, violet, or lilac color
b : a strong purple

Three Purply Colors in My Box of Crayola Crayons

I rooted around looking for my box of 64 Crayola crayons (with sharpener) to see what purples I have—"violet (purple)", "blue violet", and "plum". During the very elementary grades when receiving the 8-pack (BIG-size for indelicate handling). (Maybe I was too young to think of "violet" or the parenthetical purple, only remembering "purple" as the dominant term.) IMO, the wrappers and sticks look a lot closer to each other than the circular marks I'd made. The "violet (purple)" mark looks a lot more like the "plum" mark than the "blue-violet" mark.

A Blog Article with Three Mentions of Purple Regarding Spiderworts

Only about a week ago, a blog article mentioning some purply terms nudged me to firm up my theme about purple. From Steve Schwartzman's "Another white variant"—"white variant of a spiderwort, a wildflower that is normally purple or magenta or violet. Another purplish wildflower that occasionally shades to white is the bluebonnet".

Ride-sharing with a Snail

During a trip (October 25, 2002), I spied the critter on my rain-spattered rental car that I needed to return. It looked interesting enough that I took a dozen pictures over a period of a little less than a half hour (Oct 25, 2002, from 9:06 AM to 9:32 AM). I'm not sure it was still on the car by the time time I finished the car return process.

I noticed a few features in poring over some of the pictures. The body had a certain translucence to it. The antenna were interestingly pointed. The spiral on its shell was cute.

Snail Wrangler's "Anatomy" describes external and internal parts and includes labeled diagrams. Well, now I know those "antennae" are tentacles. The relevant page at Today I Found Out elaborates about tentacles and antennae ("feelers"). (While prepping my images to made a video, I wondered why my snail showed four "extensions"—two longer upper ones and two shorter lower ones.)

While thinking about looking up snail info, I also thought about slugs, which I thought had a lot of similarities to snails. And how! Looks like if a slug had a shell on it, it would easily pass for a snail. The shell seems to be the biggest identifier of difference between these two mollusks.

Snail vs Slug

I ran across numerous hits when I googled "snails vs. slugs". Most sites explained similarities as well as differences besides describing these animals and displaying images.

From Snail Wrangler "FAQ":

Q: What’s the difference between a snail and a slug? Are slugs related to snails?
A: Slugs and snails are very close relatives. They both glide along on a muscular foot, have tentacles. Snails have a shell while most slugs have little or no shell, and slugs with tiny shells cannot withdraw their body into it.

Q: Why are snails so slimy?
A: Snails make slime from special glands to help protect their bodies from drying out. The slime also helps the snail to adhere to surfaces as it glides along, and it also protects the snail’s foot from sharp protrusions.

Diffen's "Slug vs. Snail" has extensive info—comparison images, comparison table, and expansive explanations.

Slugs and snails are generally distinguished by the presence of a large exterior shell on the back of snails. Snails and slugs are both gastropod mollusks, and unlike most gastropods they are terrestrial i.e. found on land.

The site also describes similarities.

Both mollusks have several similar features, like eye spots at the end of slender tentacles, downward-directed mouths, and single, broad, muscular, flat-bottom feet, which is lubricated by mucus and covered with epithelial cilia.

Difference Between | Descriptive Analysis and Comparisons' "Difference between Snail and Slug" is another site with images, comparison table, and explanations, including similarities.

Snails and slugs are both members of a larger group Mullusca. This group or phylum generally includes soft-bodies animals which do not possess any type of body segmentation and often bear an external shell composed of calcareous material. …

Like snails, slugs also belong to the Phylum Mollusca. Slugs and snails both leave a silvery slime trail on the ground. Like snails, slugs are also commonly hermaphrodites. Both have one or two pairs of tentacles on their heads. They eat through radula covered with rows of teeth. Radula is similar to the tongue.

More slime info from Wonderopolis' "How Are Slugs and Snails Different?":

That slime is called mucus. Snails and slugs make mucous so that they can move on the ground. The mucus keeps their bodies from losing moisture to the dry soil beneath them. It also protects them from being cut by sharp objects in the soil. ... Because of their small size and the way they move, snails and slugs are naturally slow-moving creatures.

Note my tiled pic (left side) shows a good-length slime trail. The image is #6 of 12 of my slideshow video.

Video Entertainment (A Day at the Races)

"Snail & Slug Race"
An entertaining YouTube video of a side-by-side race between a slug and and snail. Music is abbreviated William Tell Overture, AKA Lone Ranger theme.

Another snail race—"2012 Race Night - Race 2, The Snail Race"
An 8-snail, side-by-side race. Participants were drafted when club members found them loitering at the premises. Music is a portion of "O Fortuna" soundalike and lots of "Chariots of Fire".

OK, not exactly a race—"Snail Gives Birth - Birth of a Snail"
The parent snail in the video resembles the one that rode with me.
