Fungus or color change?

Sorry if the picture is hard to read, she’s hard to get a picture of. She has a new white spot on her head, but there’s no ammonia in her tank and her temperature and ph are fine. Her appetite is unchanged but the spot appears to have gotten bigger. She does change from black to gold speckles so I’m wondering if this is even fungus. What should I do?

Here’s a clearer picture. She has a spot on her elbow too

I wouldn't worry about it, it looks like just some clusters of iridiphores (shiny pigment). Very pretty!

Fungus tends to be white/greyish and will be raised and cotton-looking.
