This is a video of me talking about a couple of the problems with how Designer deals with color, and likely Affinity Photo as well.
And this video should explain at least somewhat well why the gradients are too dark.
If there are any Affinity devs active here, a response/acknowledgement of the problem/solution from them would be appreciated. Thanks!
P.S. Shortly after I made this vid, I actually did go and buy AD. So I hope even more now that these problems get fixed. Like the point I tried to make in the video, would these issues really be that hard to program out?
