Cold trim all day, way less mess and the knife just glides.

Man, straight up, screens lie to you in ways a swatch book never will because of backlighting and color temp, so your paper book is still the real test. Honestly if more people kept one next to their desk they'd stop wasting money on reprints.

Oh man, I feel this one deep. I read a thing a while back from the Nielsen Norman Group about color and accessibility, and their main point was that color alone should never carry the meaning, you always need a second signal like an icon or text label. Blue and orange is actually a solid combo for colorblind users since it's the most common pair that holds up, but the problem is orange screams "caution" to pretty much everyone else. What they suggested was keeping your success and error text but adding a checkmark or an X next to it so the color is just backup, not the whole message. That way your boss sees the checkmark and knows it's fine even if the orange bugs him. You could also try blue for info, green with a check for success, and red with an icon for errors, since the icon does the heavy lifting. The color pair matters way less than people think once you stop relying on it by itself.
