Autunite

LW & SW

Bright yellow-green glow due to uranium content.

Scheelite

SW

Can have yellowish tinge depending on impurities.

Sphalerite

Can range from amber-yellow to orange-red.

Fluorite (Rare)

LW

Deep amber or orange in some European and African locales.

Tugtupite

SW

Can exhibit orange tones alongside red/pink.
