Tiny bubbles is a high quality game. Definitly worth trying and if you do, it probably would help you to understand what I am saying. It has a color-blind mode which actually works without symbols or patterns. The bubbles in the game move and combine like real bubbles, and they have reflections and shading that give them a 3D appearance. Imagine that the bubbles are in a room with a window on the right, and you see a reflection of the window in the bubbles. Also they have colors that combine according to natural rules. There are eight colors that matter:
Red, Yellow, Blue are primary. Red plus Yellow is Orange, Yellow plus Blue is Green, Blue plus Red is Purple, and Red plus Yellow plus Blue is Brown. When you add a color to a bubble that already has that color mixed in, the bubble color does not change.
In the color-blind mode the bubbles without color are drawn without reflections. The other seven colors have been chosen so that people with various types of colorblindness can tell them apart.
It seems to me there is a way to show the differences between the various bubble colors that would work even with a greyscale screen and still without symbols or patterns. Expanding on the clever idea of showing the colorless bubbles as having no reflections, what if the room had three windows, one for each primary color, and a bubble reflects the windows that correspond to the colors mixed into the bubble. Then, by paying attention to the window reflections, one could tell which colors are mixed into each bubble. See the drawing below. In the drawing I have also shown the bubble types Shadow and Wild, which are not part of the color system. Also sometimes the colors are indicated by color swatches without shading or reflections. A solution there is to put reflection spots on the swatches.
