Although there are many warm yellow and scarlet options, there are fewer options for bold orange. Many artists choose to omit orange for their palette as bright oranges can be mixed from warm yellow and scarlet options.

Color List
Roughly yellowest to reddest:
- Benzimida Orange (PO62) – most yellowish
- Cadmium Orange (PO20)
- Perinone Orange (PO43)
- Italian Orange (PO5)
- Transparent Pyrrol Orange (PO71, PO108, or DPP)
- Pyrrol Orange (PO73) – most reddish
My Thoughts
Necessary slot? No, orange is pretty easy to mix. I especially like the oranges mixes from Quin Coral (PR209).
Mix Your Own: Orange Yellow + Magenta, Rose, or Pink
