Why am I losing the effect/color when going from duotone, tritone, etc. to rgb? Not using spot color, just using the picker to select the colors. The when I try to change modes to RGB so I can save as a jpg it goes all b&w. Never had this issue before. This seems to happen only when I use the artistic filter graphic pen. I go to graphic pen use it, then grayscale, then duotone, then rgb.
Could you please post a screenshots (with the Channels Panel visible) to illustrate what’s going on?
Why do you go the duotone-step at all?
If an RGB-image is the intended result shouldn’t you be able to achieve pretty much the same effect with some combination of Layers and Adjustment Layers in RGB straight away?
Quite possibly one Gradient Map Adjustment Layer might suffice.
