Shows brush strokes at 8 bit and 16 bit, with Krita brush engine and MyPaint brush engine respectively
Additional image demonstrating it is not a transparency issue |

I tested on Windows 10, Krita 5.2.9 Quick brush engine b) Basic-1 brush MyPaint engine Wet Paint Plus brush Both brushes create the same colors in 16bit (I tried with gamma 1.0 icc profile and gamma sRGB icc profile). Note: The Wet Paint Plus has smudge settings active - you might need to make multiple strokes on top of each other to get to full saturated colors. Created attachment 180128 [details]

Thank you for your input~ Interesting to see that our experience is not the same. I have supplemented another screenshot demonstrating that it is not a saturation/opacity issue (I also used my mouse to rule out a pressure sensitivity issue with my art display). I also retested with both sRGB-elle-V2-srgbtrc and sRGB-elle-V2-g10 and got the same results as before. |
Created attachment 179577 [details] Shows brush strokes at 8 bit and 16 bit, with Krita brush engine and MyPaint brush engine respectively SUMMARY When using any myPaint engine brush, any color applied comes out brighter than what was picked if using 16 bit integer/channel color depth. Tested with included myPaint brushes such as "Wet Paint Plus" STEPS TO REPRODUCE 1. Set image to RGB/Alpha, 16 bit integer/channel mode, default profile 2. Pick myPaint engine brush and any color 3. Paint at max opacity OBSERVED RESULT The applied color will come out brighter than what was picked, regardless of pen pressure EXPECTED RESULT The picked color should be applied when using max pressure SOFTWARE/OS VERSIONS OS Windows 11 Krita Version: 5.2.9 (git ac6cae8) Installation type: installer / portable package Hidpi: true Qt Version (compiled): 5.15.7 Version (loaded): 5.15.7 OS Information Build ABI: x86_64-little_endian-llp64 Build CPU: x86_64 CPU: x86_64 Kernel Type: winnt Kernel Version: 10.0.22631 Pretty Productname: Windows 10 Version 2009 Product Type: windows Product Version: 10
