I'm not colourblind enough to be "legally" colourblind (that is to say I don't have an accurate diagnosis) but I still feel your pain. I particularly hate status indicators that are orange/green, rather than red/green, because I just cannot tell them apart at all, where as at least the red gets a bit darker so that I can tell that "dim is off", for example. Nintendo seem to be pretty bad for this, at least with the Wii, because the LED is forever this weird yellow that looks like what I'd call yellow, but actually isn't, and I had to actually switch to the input on the TV just to check if it was switched off or if I'd managed to catch the button while dusting under the TV.
There are varying types of colour blindness. For example, there are the "opia" and the "omaly" types. For r/g and y/b these seem to have different ramifications.
Mostly the "omaly" types can get by without too much fuss since colour differentiation is more muted and the "opia" types affect more of the spectrum and more difficulty differentiating if they can at all.
It's more nuanced than that, but generally speaking it tends to work out that way.
