The SFOTH towers in Roblox are typically described with these colors: red, purple, blue, tan, and magenta. In the SFOTH IV wiki, those are listed as the five portal colors for The Heights.

What that means

  • Red.
  • Purple.
  • Blue.
  • Tan.
  • Magenta.

Extra note

If you meant the map’s overall look rather than the portal colors, SFOTH- inspired maps are often described as having an orangish-red and brown color scheme.
