I don't have colour blindness, I have a colour calibrated display, and I find it hard to differentiate between them.
Also, Firefox blocking Canvas elements does something really funky to the hex tiles making it harder. Allowing access does make the tile background change to pink/yellow-green instead of them all being lilac/lavender/purple animations.
The colours make it too difficult for me on a good display, and the dancing 'thing' (wheat?) doesn't help.
Seems to be fine on my firefox with ublock enabled. Though the hexes sometimes are confused about which groups I'm modifying, which I'm not sure if that's a firefox thing or not.
Color also seems fine to me. Horse is bright blue and the other is lavender.
It seems that you're indirectly citing my comment, so I have to reply.
You really have trouble differentiating between 5fd3ff and b58cff? These are dramatically different hues (65 degrees on the colour wheel).
I mean, maybe the site is A:B testing different hue combinations, or there is a technical fault happening for some users, but if you really have trouble differentiating those two hues, one of your two declarations at the beginning of your comment must be false.
Those two colours have a contrast ratio of 1.50:1 according to https://www.accessibilitycolor.com/#fg=5fd3ff&bg=b58cff - the baseline for WCAG is 4.5:1 for AA standard. Look at the text on the background as calculated and tell me that these are good colour choices... The colourblind examples this colour pair gives are even worse.
So yes, while I can tell the difference between these two colours doesn't make it good to play or an acceptably accessible choice even for those with good colour vision. They are objectively too similar.
"I find it hard to differentiate between them." ... "The colours make it too difficult for me on a good display"
Either you are in denial about a personal vision deficiency, or you bought your display on Temu. Or you're just trying to show some sort of vision solidarity with the colour blind, which, fair enough. We should all be more thoughtful of accessibility.
We all know that these aren't good colours for the small percentage of people with colour blindness. I literally directly addressed it in my root post, to then get confirmation that the person has colour blindness. Citing a page literally regarding being accessible to the colour blind is not making your case.
They are objectively, blatantly clearly different hues to the vision normal. Which is why I addressed the comment wondering if the person had colour blindness, which they of course do.
I don't have to defend the quality of my equipment (hardware or wetware) to you or anyone else. The science says they are to similar in contrast for differentiation. If only there were other colours that could have been used instead.
Objectively different hues is bunk: #fffeff is 120 degrees from #fffffe - I defy anyone to tell them apart. It's just not as simple as hue as the only factor.
