Colours to watch for

I plan to do posts in the next few days about brain blue and brain red and brain blue yellow and brain red green.

You will have no trouble seeing brain blue but brain red green will probably be difficult, for you. No offense. Seeing brain red green is harder than being smart, and how many people are good at that not many.

When you do see brain red green, write down how it looks so you can describe it for others.

Others will be grateful for the heads up.
