Best/cheapest coloured ball recommendations please?

DX2 in orange is good, the green is very difficult to find as is the red.

yeah got one of each to try. I know what you mean about red, found one recently and although they are quite vivid they don’t how up well at all from distance.

Red/green colour bindness is very common, and are hard to distinguish even if you don't have the condition (something about proximity of cells in the eye iirc).
