> My understanding is color alone is not enough as a signal for alerts. There are enough people who have issues with color differentiation that color isn't enough.
Yes, it's standard practice that you don't rely only on color for information. But for people that can see those color differences (about 90% of the population don't have color blindness) it's a very worthwhile improvement so isn't it overkill to ignore these people? And what's the problem with tweaking the shades so they match the brand a little better?
What are you advocating as an alternative? How many colors and shades?
