Dear video essay creators. A video analysis is when you analyze a piece of media. No no look at me. A summary, no matter how thorough, is not an analysis. An analysis requires you to draw conclusions about the media such as authorial intent, real-world parallels, discussion about themes/worldbuilding/character motivation, and so much more. You have to stop summarizing something and saying that’s analysis. The Gaylors are doing more critical analysis than you. Is that who you want to lose to? The gaylors?
also in the face of people deleting their blogs, that's another reason why you guys are supposed to reblog stuff. if somebody deletes a post, your liked version will disappear, but the reblogs remain. i'm insane about preservation and archival, every single piece of art i have ever enjoyed is reblogged on my 450k+ posts main account so if the artists leave I still have their work. i even tag things (though just with the main fandom tag) so I have years and years worth of fanworks saved that the terrible general site search will never show you.
please reblog art. not just to support the artists who make it and share their efforts, but also so you have your own copy of their works saved for yourself, and the future users of this site.
Well fucks? Get to it!
I am going to a museum with my friends, I plan on taking pictures. It has a few skeletons and a lot of replicas of animals.
Would anyone be interested in seeing a selection ?
As I have been promising for years, the eye color chart is all cleaned up and ready to be shared! I'm totally ok with this being saved and passed around, that's why all my info is on it.
Basic image description is in alt, and a full transcript of all text in the image is under the cut.
This model has been in a process of expansion and tweaking for a very long time. Huge huge thanks to all the folks who contributed and hunted down photos, helped me name all the colors, and gave the final proofs!
Eye colors in cats are difficult to model because they vary to a significant extent on two axes. This is my best attempt at a general model of cat eye color based on observation and research into how eye color works across species.
Pigmentation refers to the amount of pigment in the colored layer of the iris. Higher pigmentation causes darker colors.
Refraction means the extent to which light is scattered in the structures of the iris. Higher refraction causes deeper blues or greens.
Eye colors are related to coat color, but not as closely as breed standards might have you believe! Most coat colors can have most eye colors outside of purebred lines selected to meet breed standard.
Color names are descriptive of the actual color of the cat's eyes - I chose them all to sound nice so that breeders can use them if desired. Note that breed standards have a much broader use of color names - "Amber", for example, may include much of the golden to orange range.
Colors are based on pictures of cats in full white light (such as midday sun fully illuminating the eye), and tweaked to look good on properly color-calibrated screens. Always determine eye colors based on how they look in full light.
standard eye colors possible with most pelts
Every cat is assumed to have genes that specify some genetic eye color in the main block, but certain other alleles can depigment the eyes partially or completely, creating the lower block.
Pigmentation and Refraction are modeled here as dependent on multiple genes, which seems to best fit the wide spectrum of possibilities in cats. The actual number of genes is unknown and could be very many, but for simplicity they are shown here on a scale from 1-7.
In theory, the genetic eye colors of the offspring should tend to fall somewhere between the genetic eye colors of the parents. Then, any depigmentation factors are applied, which may result in an actual eye color somewhere below the genetic eye color.
occur with phenotypes which cause depigmentation of the iris.
Gray-blues: Fairly rare coloration. The cause of gray eyes in humans is not well understood, but one theory is that collagen or very small amounts of pigment in the eye alter the scattering of light.
Blues: Most common depigmented colors. Can be caused by white spotting/dominant white, colorpoint, and sometimes mocha. There are also multiple Dominant Blue-eye (DBE) mutations known which cause blue eyes as the main effect.
Albinistic: Caused by complete albinism, which also fully depigments the back layer of the iris meant to keep light from getting through. This allows the red color from the retinal blood vessels to bleed through, and also causes poor visual acuity.
Following is a list of all eye colors shown on the main diagram. Rows are pigmentation levels starting from the highest pigmentation, refraction increases from left to right.
Main Block: Copper, Chestnut, Umber, Walnut, Earthen, Olive, Moss; Ochre, Caramel, Bronze, Serpentine, Artichoke, Fern, Forest; Orange, Amber, Brass, Peridot, Avocado, Clover, Malachite; Saffron, Butterscotch, Shrub, Spring, Jade, Pine, Emerald; Gold, Citron, Pear, Lime, Mantis, Grass, Viridian; Yellow, Chartreuse, Sprout, Laurel, Mint, Turquoise, Teal; Canary, Chiffon, Honeydew, Sage, Celadon, Aqua, Cerulean.
Lower Block: Gray-blues: Frost, Opal, Flint, Storm, Steel, Slate, Cadet. Blues: Ice, Powder, Celeste, Sky, Azure, Lapis, Cobalt. Albinistic: Pink, Mauve, Lavender, Periwinkle, Cornflower, Royal, Indigo.
Cats can exhibit a few different heterochromia types, most commonly a blue with a non-blue. The other most common cause for heterochromia appears to be localized hyperpigmentation, which can be caused by damage to the eye. It can also happen simply due to differing iris structure or unusual pigment migration within the iris.
It is also relatively common for the center of the eye to be a slightly different color, without being marked enough to constitute full heterochromia. My provisionary term for this is "dual-toned". The boundary between this and "true" central heterochromia is somewhat subjective.
For any form of heterochromia or dual-toned eyes, my recommendation for describing them is to note both colors with a slash. For dual-tones, I generally write the outer color before the center one.
Complete Heterochromia Blue/non-blue is commonly caused by white spotting/dominant white, other combos are rare.
Sectoral Heterochromia Blue/non-blue sometimes occurs with white spotting/dominant white. Can also be from hyperpigmentation.
Central Heterochromia Can occur due to hyperpigmentation, uneven pigment distribution, or iris structure. More common in certain breeds.
Dual-toned Irises Relatively small differences in central eye color are common in cats.
Iris Atrophy Iris atrophy due to old age can cause a distinctive lighter ring in the center of the iris.
