Would you mind using COL_RED instead of COL_LIGHTRED? (LIGHTRED on
YELLOW is mostly a colour contrast, thus people that only recognise
shades of grey, will not be able to discern between the colours easily
enough. [1])

I can only concur. I've made a quick mock-up, see attached file. I am
unsure if it is easy enough to discern the chequerboard pattern at the
6*22/4*16 scale of our icons, though. What do you think?

Enter colours, then look for the WCAG AA(A) information.
