How Eshka perceive and reference colour.

[top]Intro and Wavelengths
Eshka inherit different colour cone genes from their parents, usually resulting in having 1-3 different cones (monochromats, dichromats, and trichromats), with rare exceptions of none or 4+. There are genes for a total of 7 different cone ranges, resulting in a variety of visual spectrums and differentiation between individuals.
Colour is referenced based on a colour cone. As there's overlap, which cone someone uses to describe the colour of something depends on which cones they have, which cones the person they're talking to has, and what they're describing (for example, if reasonable, there's a preference for describing foliage in terms of ɲæsɛ, which covers an area between our blue and green cones, extending into UV). Then, the amount of that colour is described in terms of high, medium, low, or none (beyond the range that cone can detect). Finally, if they know it, they'll usually include which side of the peak it's on, toward lower wavelengths/UV, or higher wavelengths/infrared. If they have other cones that overlap, or know from experience where that colour is on the spectrum, they can usually reference which direction it is, but if they only have one cone in that area, they might only be able to tell the amount.
Wavelengths in nm
(most of these words are specifically for describing colour)
Here's an example of jeɪnæ with the human blue, green, and red cones for reference. The higher the line, the more colour the cone perceives at that wavelength. Left is shorter wavelengths (ultraviolet/UV) and right is longer wavelengths (infrared). The spectrum of visible light for humans is around 400-700 nm. The maximum range for Eshka is around 280-1000 nm.
Note: colour signs are based on actual left/right, not dominant/non-dominant unless stated. All signs below refer to top hands, and main hand is pointing up.
zɑkleɪ: Left hand in W (3 fingers)
untæ: Left hand in V (2 fingers)
ɲæsɛ: Left hand in POINT (1 finger)
kɔstɑ: Dominant hand in THUMB
mɛli: Right hand in POINT
jeɪnæ: Right hand in V
piɛkæ: Right hand in W
For amount of colour, the secondary hand will point to a part of the (main) hand/arm while the main hand signs the colour.
Medium: base of finger(s)/thumb
High: tip of finger(s)/thumb
The pointing hand will point with 1, 2, or 3 fingers, based on if it's the left/short or right/long direction.
Left/Short (or peak/high): POINT (1 finger)
Unspecified: V (2 fingers)
Right/Long: W (3 fingers)
[top]Writing in T'eaj
Mark the upper hands.
The top handshape is for the colour hand.
The bottom handshape is for the amount/direction hand.
If both use the same handshape, still write them both to avoid homonyms with other words which would normally combine them into one large handshape.
For elbow and wrist, the position is torso (∏). For base and tip, the position is head (⭘).
For the lower of each position (elbow for ∏ and base for ⭘), the movement curves down. For the upper (wrist and tip), movement curves up.
The movement arrow points toward the direction being pointed. So if you're pointing to your left hand/arm (using your right), it points to the left. Pointing to the left wrist would be transcribed as ╛ (double lines indicate which direction the arrow points, in this case left. Single line indicates which side it curves toward, in this case up).
