I created a layer, added R_G_B attribute, saved the file and the project, re-opened it The ColorTheming is not activated. But if I choose ColorTheming tab, I can select R_G_B attribute, which is not compatible with how R_G_B attribute works.
I fill a bug report : de-activate R_G_B attribute in ColorTheming > However, it is not possible to adjust colours from the theme colouring tab. > Only editing R_G_B field value has on effect on colours.
