Hello, from some moment Krita started show eyedropper in brush mode (by holding Ctrl) in black and white, even though I point to some color. I didn’t used this for a time, and if I pressed some keyboard shortcut, didn’t noticed that. Tell me please where is this option.
Could you show us what the tool settings are for the eye dropper: Select the eye dropper tool normally (not by holding control when the brush is active) and then select the tool options docker.
I suspect that the sample size is so big that it samples too much surrounding gray. Together with the blend mode not being 100% it could mix with the current color and then make it seem like its all in grayscale. That’s the only way I was able to reproduce it, but having a screenshot with the eye dropper tool active and the tool options docker visible would help a lot.
Another thing that could have happened is that your Group 2 Merged has a grayscale color space for some reason, this would have the same effect too. You can check the profile of a layer by right clicking on the layer in the layers docker and select properties from the context menu. You can convert the color profile of a layer by clicking on Layer → Convert → Convert Layer Color Space… in the menu bar.
Didn’t changed any eyedropper settings. Anyway, solved it by copying layer pixels (Ctrl+A Ctrl+C) and then pasted to new file (with same dimensions)
I believe it was because of reference image pasted right under the sketch. It was set to ~5% opacity but it seems while sampling color, eyedropper renders it as 100% opacity.
If I move reference somewhere left or right, I can also pick normal color (with background layer color). Thanks for collaboration.
