FastLED color palettes use HSV space to generate harmonious schemes. Use complementary (opposite hues), triadic (120° apart), or analogous (adjacent hues) patterns by setting CHSV values with hue offsets, then apply fill_gradient_RGB() or blend8() for smooth transitions between palette colors.

RGB specifies red, green, blue intensity directly; HSV separates hue, saturation, and value for intuitive color control; HEX uses hexadecimal notation. FastLED converts between them internally—HSV is perceptually uniform for palette design, RGB for hardware output, HEX for shorthand notation.

Washed-out gradients stem from low saturation or improper gamma correction. Slow performance results from excessive color calculations. Apply gamma correction to match human eye perception, use fill_gradient_RGB() instead of manual loops, and pre-compute palettes to optimize constrained hardware like ESP32.

Optimize by pre-computing palettes rather than calculating colors frame-by-frame, using 8-bit color math instead of floating-point, minimizing blend operations, and understanding hardware constraints like LED count, timing, and current draw to balance animation smoothness with power efficiency.

Yes. Gamma correction compensates for human eye's non-linear brightness perception and LED hardware response. Apply it during palette generation or color output to ensure LEDs display perceptually accurate colors matching your design intent across different brightness levels.

Color order (RGB, GRB, BGR, etc.) depends on your LED controller's wiring and chip type. FastLED supports multiple orders; choose the one matching your hardware datasheet to avoid color shifts. Incorrect order causes red-to-blue swaps or other visible color mismatches in animations.
