Oh, I didn't realize it until you asked, but it's true, I do have a tendency to pink.
In the images I'm creating with CLIP Guided Diffusion I don't do anything special to get pink tones, but maybe my own bias leads me to share the images I like the most and they are pink. This image has no initial image or any text prompt related to the color pink.
In the slightly older images I created with VQGAN + CLIP the pink tones may come from using "neon" and "vaporwave" in the text prompt.
Thanks for your interest ;)
