Because yours looks like this?
CBD distillate….or many of the appropriate diluents you were recommended…
Or even crude…
Or you know, actual D9 distillate…
Presumably they want darker distillate because they don’t want converted oil….which is generally either bizarre shades of pink/purple, or almost water clear.
Extracting at rm temp with ethanol will get you green, but you can absolutely get that to “amber” with sunlight and the appropriate dilution.
You won’t need much flower.
