FLASH GORDON will tell you my colours clash so I don’t know if you want to take my advice but…my Mother was an art teacher in London and she would say look at it’s close neighbour in colour- so if you have grey - it is close to black with a mix of white and of course orange is close to red.
yellow is a base colour on it’s own and can obviously change your orange closer to itself away from red.
What was your question again? :E~~~~~
