Color rendering different

I am using the RGB codes for Dunn-Edward’s paints but they are rendering very different. The swatch on the paint looks right however when it paints it turns much much lighter. Also a deep red color is rendering magenta? Am I doing something wrong?

Hi Ingrid,
Can you post your pictures before/after so we can see?
When using RGB codes, the app is geneally “RGB accurate” meaning its going to hardcode the color to be accurate, but sometimes that AI can ‘misread’ the shadows or darkness/lightness of the existing color so as a result will guess a darker or lighter shade than it would be in reality.
This can be especially true if the mask is not good.

Thanks
