The reasoning on the first two points is the same, yes, simply because I agree with Ethan’s. The two big differences are: I’m aiming for perceptually uniform colour differences instead of the same luminance and my background colours are directly sampled from daylight.
For the colours, this means uniform chroma and hues that aren’t hand-picked but optimised (on top of that using a more hue-accurate colour space).
I’d argue there’s enough of a difference, especially in the visual result, to make this more than an iteration, but even if it was simple iterative, there’s nothing bad about that and it can still be valuable work without being plagiarism .
