FL_PROGMEM

const TProgmemRGBPalette16 HeatColors_p FL_PROGMEM   PROGMEM

PROGMEM keyword for storage.

Approximate "black body radiation" palette, akin to the FastLED HeatColor() function.

HSV color ramp: blue, purple, pink, red, orange, yellow (and back).

HSV Rainbow colors with alternatating stripes of black.

HSV Rainbow.

Forest colors, greens.

Ocean colors, blues and whites.

Lava color palette.

Teensy 4.x (__IMXRT1062__) workaround: Teensy core defines PROGMEM as __attribute__((section(".progmem"))), which causes GCC to emit "section type conflict" errors when a single translation unit contains FL_PROGMEM variables of different types (e.g. CRGB, float, i32) — see the fl.fx+ unity build that aggregates colorpalettes.h, sin32.h, and mic_response_data.h. Teensy 4 has a unified linear address space and places const data in .rodata (flash) automatically via the linker script, so the section attribute is unnecessary on this platform. Emitting empty FL_PROGMEM keeps user code that uses Arduino's PROGMEM directly unaffected.

Basically, everything but the greens, which tend to make people's skin look unhealthy. This palette is good for lighting at a club or party, where it'll be shining on people.

It's recommended that you use values 0-240 rather than the usual 0-255, as the last 15 colors will be "wrapping around" from the hot end to the cold end, which looks wrong.
