I'm mostly after a dark mode out of aesthetics and eye strain, don't have any colourblindness issues.
Took a quick look before posting at WACG compliance. Taking a screen snip and putting the image gave a red flag for contrast. Not across what the result inferred or if the method was valid... I assume the platform is up to speed with these things, so we can consider this to be a purely aesthetic request.
Thanks for the analysis and support!
