Hi Renee,
I don't think I understand your question. Pseudobond files (pb files) and color keys can both have any colors, including defined with hex codes, etc., and those two things (pseudobonds and color keys) are not tied together in any way.
Also you mention "confidence" which makes me think maybe you are talking about AlphaFold-predicted structures and maybe PDB files instead of "pb" files. PDB files just contain the structures (3D atomic coordinates) and don't have colors in them, although of course you can display them in ChimeraX with whatever colors you like. If you are displaying AlphaFold-predicted structures, there is a default ribbon coloring which maps to pLDDT confidence values, and the color key can show that default coloring:

But again, you can color them any way you want, and you can also make a color key that shows any colors that you want.
The pLDDT values are put into the B-factor column of a PDB file, so if you open an alphafold-predicted PDB file you can use the ChimeraX "color bfactor" command and with the "palette" option of that command, specify whatever colors and color->bfactor value mapping that you like, and with the "key" option of that command, automatically create a color key that matches whatever palette coloring that you specified. The command and its options are explained in the help:
<
https://rbvi.ucsf.edu/chimerax/docs/user/commands/color.html#byattribute >
The coloring by attribute such as bfactor value in ChimeraX is gradual, i.e. in the default pLDDT confidence coloring, pLDDT 100 = blue and 90 = cornflower blue, and values in between 100 and 90 are between blue and cornflower blue, and that is shown by the color key.
I hope this helps,
Elaine

I'm wondering if there's a place to look at the degree of confidence based on color somewhere or a way to have the output with the general color like red, blue, orange, yellow, etc. instead of very specific shades.
