How to colour correct without losing values?


Recommended Posts

In photoshop you can set your adjustment layer in colour mode so you be able to change colours of the image without losing values. But it didn’t work in affinity photo on ipad. So my question is is it possible somehow to do colour correction without losing values?

By losing I mean they are changing.

I understood that you meant something was changing, but what are “they”? :/

I don’t want to affect values of my image, only colours

Do you mean that you only want to affect the colour values, not the opacity?

Think of using HSV to describe colors, or even HSL. Sounds like Cul wants to adjust Hue (H) and Saturation (S), without affecting Value (V).
