Understanding Colors for AI Artists

Why you need to grasp RGB, CMYK and HSL colors

With AI Art, you write what you want and there is no need to know traditional artist stuff like color models, right? Wrong, if you really want to get good at AI Art, you need to actually learn the usual stuff that any artist has to master.

In this regard, the current article isn’t specific to AI artists, but to anyone who would like to get into photo editing or digital painting. But it is written from the perspective of someone who primarily do AI art.

Let me give some context for why an understanding of colors matter. Consider the title image of a futuristic female astronaut. It was generated with a text prompt containing text similar to the one you see below:

woman in shiny hard yellow moulded plastic futuristic armor, 
helmet, quantum effects, neon lights, space futurism

From this text, an AI art generator tool built around, for instance, the Stable Diffusion library, can generate a variety of images upon the same theme. If we add an image to guide the process, we will typically get an image which are smaller or larger variation upon the starting image depending on your settings. This approach is what we usually refer to as image to image.
