sometimes an ICC profile does not reproduce certain (mostly strong) colours not 100% correct. Is there a way in RT to select such a colour with the mouse pointer and then adjust its HSL values throughout the image? I have looked through the menus and did not find anything like that.
I am using ICC profiles created with Argyll for my scans of slides. Although the profiles produce very good colours overall it could happen, that e.g. a strong red comes out somewhat too saturated compared to the original and I would like to reduce the saturation a bit.
