Have any neutral/masculine leaning names related to the sun/heat, desert, and/or yellow?
Yup! Sorry it took so long, I'm kinda goin' through some stuff rn. But anyways, here are your names.
Apollo (Greek god of the sun, as well as many many many other things)
Blaze (or Blaise if you prefer that)
Dustin/Dust/Dusty
Halo
Sol (or Solstice, fairly obvious [BTW there are lots of variations of Sol])
Ash
Mesa
Dune
Helios (Greek Titan of the sun)
Coal/Cole
Sahara (the desert, but this also just... means desert, it turns out)
Ochre (means pale yellow)
Phoenix
Mirage
Bee (Kinda related to yellow, ig? Idrk, but I thought I'd put it on here)
Tawny (shade of orange/yellow ish)
Ember
Sandy
Flint
Some of these are just things that kinda give me those vibes, but I hope this helped! Anyone, feel free to add your own ideas in the comments.
