Hello zniavre. Out-of-interest, do you know (and would you be willing to share) which variant of colour-blindness do you have?

I think the intent from a design point-of-view would be that the states would always vary in luminance and saturation, so that in the case of the chrominance not being seen, there is still sufficient variance compared to the base state. Clearly that's failed here.

I don't know that we can ship a fix for Ubuntu 11.04 itself, but it's something I think we'd like to look at during the next cycle up to Ubuntu 11.10, and in the mean-time I hope we can direct you on how to workaround (but I confirm that from memory, the BFB/distro-icon uses a hard-coded shader to convey the state rather than loading a recoloured variant of the icon).

This site,<> , is useful for choosing such colors. It has the option for color blind selection.

Or maybe we could make this a variable in the theme, use the blue by default and then allow folks to change it.
