seems that there is a serious misconfiguration in our color input pipeline in Blender. Baseline diffuse color and color mapping with a texture does not produce the same result when the same color is used for both, which is wrong. Both should produce the same result.
On the image attached, upper green is sourced from a plain sRGB #8aa08f green texture and lower green is base diffuse color using the same #8aa08f green, they should look the same. Blender color management is enabled, 2.2 gamma is used for color inputs and sRGB space color is used for texture input in texture panels. If bug is confirmed, maybe it also concerns other texture or base color inputs. It is a pity this bug has gone undetected for who knows how much time, since it has retroactive consequences for scenes configured with the bug active.
