Color Cube

Let's slice our Color Cube (photo on left) into sixteen layers (0 to 15=f) perpendicular to the green axis. The top layer (bird's eye view below) has 256 colors. All of them composed of 15 units of light. Let's look at the arrangement. We have bright green (hex code ff-0000) in the lower left corner and yellow (ff-00-ff), cyan (ffff-00), and white (ffffff) in the others. As we move in a straight line from green to each of the other corners, we are adding blue (horizontally) and/or red (vertically) units of light. They interact with the green light. Each unit of red combines with a unit of green, converting it into a unit of yellow light (r+g=y). Likewise each unit of blue converts a green unit to cyan (b+g=c).

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

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

Above are some other versions of "green". Let's mark them (or their upperward projection) with an "x" on the top layer of the Color Cube (below).

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

What about some other shades of green? Where are they? What are their proportions?
