Hi Niels, The initial model colors are defined in chimerax.atomic.colors as a list named atomic_color_names. That list is: ["tan", "sky blue", "plum", "light green", "salmon", "light gray", "deep pink", "gold", "dodger blue", "purple"] You can use Python code to replace that list. I have attached a Python file (start_colors.py) that replaces that list with ["khaki", "purple", "dodger blue"]. You could obviously edit the code to put in any color list you want. Then you could put "open start_colors.py" in the list of commands that ChimeraX executes at startup (under Preferences/Settings→Startup) to have them always apply. Just so you know, if you have N colors in the list, then the first N model IDs will get those colors. For models with IDs higher than that, ChimeraX will try to use a color that contrasts with the colors in the list, the background color, and the selection-outline color (green). --Eric Eric Pettersen UCSF Computer Graphics Lab

Niels,
There's a feature in my SEQCROW plugin that might do what you want. In the settings (Favorite/Preferences -> Settings... -> SEQCROW), you can define commands to run when a model is opened. It's not advanced enough to cycle through different colors for different models, though.
Best,

[EXTERNAL SENDER - PROCEED CAUTIOUSLY]
Hi Elaine,
Is there a way in chimera X to change the initial colors preset for new models?
I’m not into the default tan color, so I end up changing the color immediately every time I open a new model.
In previous versions of Chimera, I had disabled color by model and set all new models to open with grey. In pymol, I defined the colors for the first 10 models I open in the startup script, which is even more convenient. Having the option to have the default to color by chain could also be nice if that is possible. I tried some workarounds like redefining the tan color, but it appears that is not allowed.
