For those that want realistic metallic colours, I am posting here a list of the Hex codes. I have tried them all in WFD and they’re all on point.
Note: To use these, when picking your fill or stroke colours, click on RGB mode. There should be a box for Hex codes. Put in the code you want and press Enter (that part is really important). It’ll switch the colour to the one represented by the Hex code. Just add a brushed metal effect and you’re done.
Anyways, here are the codes:
Metallic Gold - #D4AF37
Pale Gold - #E6BE8A
Old Gold - #CFB53B
Vegas Gold - #C5B358
Rose Gold - #B76E79
Platinum - #E5E4E2
And Silver - #C0C0C0
Hope this helps for anyone, especially beginners, needing realistic metallic colours.
