RGB Color Wheel | RGB Color Picker Tool | RGB Color Harmony Generator (Complimentary, Analogous, Triadic, Tetradic, Split-Comp)
The RGB Color Wheel is an interactive tool based on the Red-Green-Blue additive color model — the system used by every digital screen, monitor, and web browser. Unlike the RYB model used by painters, RGB is an additive color model where mixing all three primaries at full intensity produces white light, just like how pixels combine on your display.
Spin the wheel to select any hue, adjust saturation and brightness with dedicated sliders, or dial in exact values using the individual R-G-B sliders. The tool instantly shows the corresponding HEX and RGB values so you can paste them straight into CSS, Figma, or any design application — all running 100% in your browser with nothing sent to a server.
Click or drag anywhere on the wheel to pick a hue. The selector follows your cursor for real-time feedback.
Generate complementary, triadic, analogous, split-complementary, and tetradic harmonies from any base color.
Fine-tune your color with individual Red, Green, and Blue sliders — each with a color-coded gradient track.
Click any HEX or RGB value to copy it to your clipboard instantly — ready for your next project.
On the RGB color wheel, complementary colors are the two hues that sit directly opposite each other — exactly 180° apart. In additive color, an RGB complementary pair adds up to pure white light: place them side by side and each color appears more vivid; combine them as light and they neutralize to white. Web designers, UI engineers, and digital artists use these pairs to create high contrast that pops on screens.
The three classic RGB color wheel complementary pairs are:
The cornerstone pair of digital color. Used in 3D anaglyph imagery, error-state UI patterns, and any design needing warm/cool tension on a screen.
The most vivid contrast in RGB — heavily used in chroma keying, glitch aesthetics, and Y2K-era digital design for maximum visual energy.
A high-visibility pair found in safety signage, sports branding, and warning UI states. The wide value contrast makes both colors stand out clearly.
To find a complement on this tool, click any color on the wheel and read the Complementary swatch in the harmonies panel — it always points to the hue exactly opposite your pick. Use the saturation and brightness sliders to soften a complementary pair into a tonal palette, or push both to full saturation for maximum visual impact.
