As my initial post probably was not formulated clear or extensive enough (and english is not my first language) and was consequently somewhat misunderstood by @AhabGreybeard , I want to elaborate a little bit and also want to make sure to clear up possible misunderstandings:
-
Dear Krita users who previously used CSP and who requested for the brush cursor color in Krita to resemble the color behavior of the Brush Size / Brush Shape cursor in Clip Studio Paint Pro: I am not OPPOSING your request, I am just arguing against the current brush cursor custom color options, as they currently exist in Krita, to be deleted, changed (“updated”) or disabled in favor for including the CSP brush cursor color behavior. I am NOT against the CSP brush cursor color behavior being added as an ADDITIONAL option while at the same time keeping the brush cursor custom color options / behavior, as it currently exists, is included and is established in Krita.

Before changing to Krita, I worked with Clip Studio Paint Pro, Photoshop Elements and Affinity Photo. I suffer of migraine and regularly got migraine symptoms like irritation, distraction, auras and headaches when working extended time with those other three painting programs and painting with fast brush movements and / or large brush diameters, on a large screen and using the circular brush size cursor (which I need to use to have satisfying control over the brush). I came to the conclusion that the cursor constantly changing colors and brightness in those programs lead to a “flickering lights effect”, which is a common trigger for migraine. I researched which painting programs would allow me to choose and fix the color of the circular brush size cursor to a single dark color, preferably black, to avoid the migraine triggering “flickering lights effect”. I found out that Krita is the ONLY painting program available which allows to choose a custom color for the cursor. I tried out Krita and found out that although the circular brush size cursor still changes colors when using any color besides black, the circular brush size cursor does not change colors and simply remains fully black all the time when choosing the custom color black. I then tried out painting extensively with Krita with the custom color black chosen for the circular brush size cursor with the obvious result that I don’t get any migraine symptoms / headaches WHATSOEVER, no matter how long I paint, how fast my hand movements are or how large the brush diameter is. 12% of the population suffer of migraine, “flickering lights” are a common trigger for migraine (responsible or co-responsible for about 40% of migraine attacks), and Krita with its current brush cursor custom color option (and black chosen as custom color) is the ONLY available solution for migraine patients who want to avoid any migraine triggering “flickering lights effect” brush cursor behavior while painting digitally. I am sure that there are a lot of migraine patients who use digital painting programs like PS and CSP and regularly suffer headaches / migraine attacks due to not understanding that they expose themselves to the migraine triggering “blinking” or “flickering lights effect” due to the cursor behavior of constantly changing color and brightness back and forth when painting in those programs. How many migraine patients might be there who, while suffering already from a migraine attack, try to calm down through painting in CSP or PS, and instead of easing their symptoms actually worsen them.

I researched the topic online and found out that there are other people who paint in CSP or PS, and who complain online that they are not happy with the brush cursor color behavior in CSP and PS, who would be much better served with the brush cursor custom color options as they are currently implemented and available in Krita, and who would probably like me change to using Krita instead of CSP or PS, if they actually knew of the current Krita brush cursor custom color options.
Here are some examples:
Screenshot 1: Clip Studio Paint Pro user and possible migraine patient complaining about headache through color changing Brush Size cursor in CSP:
Screenshot 2: Clip Studio Paint Pro user feeling distracted through color changing Brush Shape cursor in CSP:
Screenshot 3: Photoshop user wants to be able to choose a custom color for Brush Size cursor to make it easier spottable in PS:
