My colorblind brother in law picked my palette apart in 4 minutes flat
So my sister's husband came by Sunday for a cookout and I showed him the mood board for a little coffee stand logo I'm messing with, mostly greens and a warm tan. He's red green colorblind and he goes "cool, so the two greens in your little circles are the same color right?" I pulled them up side by side and they were 6 points apart on the hex chart, which I never would've caught on my own monitor. He said when the shades sit close like that it just turns into one flat blob for him, and that a big jump in lightness is what actually reads. Spent an hour after he left running everything through a grayscale check and half my palette fell apart. Does anyone here build in a real lightness gap on purpose, or do you just do the squint test and hope?
Six hex points apart and he caught it with his eyes while you needed a side by side comparison on screen? That is wild to me. I keep thinking about how much stuff I have approved off a single monitor and never once checked in grayscale. Half your palette falling apart after one check is the scary part, because that means it was probably already broken for a chunk of people and nobody said a word. Building in a real lightness gap on purpose makes way more sense than the squint test, since squinting only helps if your own eyes are the weak spot. My guess is most of us just hope and ship it.
