I believe it’s a horror movie except not so creepy. I saw it several years ago when I bought it in one of those cheapy used movie bins. It had a woman artist, I believe painter, who was drawn to seclusion from boyfriend and friends due to a demon. I believe he compelled her to paint this forest themed world with the colors red, white, and black. I think the demon ended up falling for her and when she slept she would end up in the painting with the demon. He would watch her but knew she’d be afraid of his looks so he disguised himself as her boyfriend I think. The colors used were a major part of the theme again red, white and black.
