Yes, as simple as the heading, anything red, orange or yellow; flowers, spines or anything else. Photos taken at any time, so should give a chance for everyone to enter.
Here's a yellow flower to start the ball rolling

Nothing too fancy, but, as it happens, my Lapidaria margaretae is flowering for the 3rd or 4th day at the moment, fits the theme pretty well and I have a photo at hand:

PS: The flower won't open more as the top leaf is on the way

This is definitely yellow.
Conophytum tantillum amicorum

Rebutia

I know I just posted this, but here it is again, since it qualifies as yellow. I may have something else coming up tomorrow.

This was the flower I was waiting for until tonight. Had to get on all fours, then down on my tummy to capture it. The fragrance was intoxicating.

I have this as Lithops helmutii C271

A little orange and yellow.
Conophytum uviforme ssp decoratum

And yellow from earlier this year.
Parodia magnifica, or Notocactus magnificus if you prefer.
