If I understand that you are asking about "red hot" as in "really spicy" there are two ways to say it. "Muy picante" is a formal and proper way of saying this. "Muy caliente" is a more lax and common way to say it, but out of context it is usually used to describe attractive members of the opposite sex.
Chiles Rojo Vivo. But since Red Hot Chili Peppers is a name, you would just say Red Hot Chili Peppers in spanish
"gato caliente" means Hot cat in "spanish"
"Pelirrojo."pelirrojopelirrojo/a
Hot date - fecha caliente
calor [ka'loɾ]
"Tengo calor"
Francisco
Hace calor
Well, it's not exact but to say You're hot in Spanish it is "as tu es caliente" I hope that helps...
'Red' in Spanish is 'rojo.' It also can be "colorado", or if referring to hair, "pelirrojo".
You can say "Bueno y caliente".
"Todas las chicas deben tener labios muy rojos y tacones rojos/zapatillas rojas"
