Where is Cyan?

Color Cube
This slice of the Color Cube (photo on left) is not flat. There are 256 colors. All of them composed of 15 units of light (green or blue). Let's look at the arrangement. We have bright cyan (hex code 00-ffff) in the lower left corner and green (00-ff-00), blue (0000-ff), and white (ffffff) in the others. As we move in a straight line from cyan to each of the other corners, we are subtracting green units of light (horizontally) or blue units (vertically) units.

Combining red units with cyan converts that same number of cyan units into white units (c+r=w). That's what happens when you move diagonally from the cyan corner to the white one. This diagonal line divides our layer into two trianglular areas: a green area and a blue one. As you move around inside each area, you flip some of the 15 units of light. Moving perpendicular to the cyan-white line flips cyan units to white as you move up and to the right. It flips white units to cyan as you move in the opposite direction (down and to the left).

Inside the Green Triangle, moving horizontally (perpendicular to the green-white line) flips green to white if you go right, and white to green if you go left. Moving vertically flips green to cyan (down) OR cyan to green (up). Inside the Blue Triangle on the other hand, moving vertically flips white and blue, while moving horizontally flips cyan and blue. What do you suppose happens when you move diagonally from the green corner to the blue one? As you move through the Green Triangle, you flip two units of green to one cyan unit and one white. After you cross into the Blue Triangle, you flip one cyan unit and one white unit into two blue ones.

This is the cyan "pallette". You can use
green OR blue, but NOT together.

What about some other shades of red (including pink)? Where are they? What are their proportions?
