what colour code suit for "GOLD" ?
need to use for gradient tool in photoshop :)

Gold is not a real color, but it can be effectively tricked more in CMYK but RGB as well

Here are some combos:

Pantone 723
---------------------
CMYK 0-43-97-17
RGB 186-117-48
Web Safe CC9933

This link is good:

RGB: FFE600

True Metalic:

Gold RGB: b48c00
Gold CMYK: 30-41-100-5

Hope that helps
