I was in krita, (this happened multiple times) and I import a greyscale lineart. but when I go to turn it off and I come back, choose a color and paint with it its still in greyscale. help! Reproducible: Always Steps to Reproduce: 1.import greyscale base/ thing 2. turn greyscale off 3. choose a color (lets say blue) and color, on mine its still grey. Actual Results: the result still happens. Expected Results: it should have came out of greyscale and colored blue (or other color instead) my laptop is a hp windows 10 and I use this for my art so I would LOVE LOVE LOVE for you to fix it!
Make sure the image is RGB and so are all layers -- use image/convert colorspace to make sure. In krita, it's possible for the image to be one colorspace, and some layers to be another.
