Hi, this is a bug I met while creating a simple vector artwork on Krita 4.2.6:

To reproduce:
=============
1. Create a new canvas, default New File RGB/8BitInteger/sRGB-elle-V2-g10.icc , 512x512px.
2. Add a vector layer.
3. In the top bar, pick this deep blue exact color: Red=0 , Green=8 , Blue=222
4. Draw vector squares on the vector layer.
5. Create a new paint (raster) layer.
6. With same color, paint circles on it...

Result:
=======
The color are really differents but they should be the same. This bug also affects color picking between raster and vector objects.

Note: if you export the vector layer as SVG; Inkscape shows the right color.
