If you want to keep using capital letters to define "constant" variables, you might want to either:

• deactivate N806 globally in the config file;
• add skip comment # noqa: N806 when such variables are defined

IMO keeping full capital variables when dealing with constant variables is a good thing and I would recommend it. Note that this would require to revert some changes, e.g. LOG, R, G, ``B`
