How to play
Each round shows a hidden target swatch. Drag the RGB sliders to build your best match, then submit to compare the result. This is the same precise engine as HEX Guess, but the framing here focuses on RGB practice and visual calibration.
Why play this mode
Thinking in RGB helps players understand what a color is made of. A small change in blue can make a neutral feel cooler, while a shift in green can make the same hue feel more natural or acidic.
Who this is for
If you work in design, frontend, branding, or illustration, or you simply want a more focused browser color game, this dedicated page is a cleaner fit than the homepage.
Go deeper
Use the Color Games hub for broader play intent, or the Color Tools hub for converters, contrast checking, and utility searches.

For a different style of visual training, keep going with Color Memory Game, Spot the Different Color, or Color Sorting Game. You can also move into Color Connect. For tool intent, you can also move into HEX to RGB Converter and the WCAG Contrast Checker. For a broader overview, visit the Color Games hub and the Color Tools hub.
Extra context
If this is your first time on this page, these extra sections help explain how this mode differs from the homepage daily challenge.
This page is intentionally framed as an RGB color game, not just another copy of the HEX route. That lets it match players who think in channels, sliders, and screen color mixing rather than named color codes.
RGB sliders make cause and effect obvious. When you change one channel and immediately see the swatch react, the page becomes useful for visual learning as well as fast replay.
Utility hub
Use lightweight utilities alongside the game: convert between HEX, RGB, and HSL, then check contrast before you ship.
Progress tracking
Track your strongest sessions, compare daily scores locally, and prepare for synced rankings once login-backed records go live.
Everything you need to know about the game and how it works.

Yes. The daily page uses a date-based seed so every player gets the same target on the same day.
Yes. Planned follow-ups include streaks, social sharing, opposite color mode, and palette matching.
Yes. People search for color guesser, colour guesser, guess color, color puzzle, and color game, but they usually want the same thing: a fast browser game that tests how well you can match colors.
