What RGB values tell you
RGB (Red, Green, Blue) is the native color model for digital displays. Each channel has a value from 0 to 255, giving 16.7 million possible combinations. RGB(255, 255, 255) is white; RGB(0, 0, 0) is black; RGB(255, 0, 0) is pure red.
When you need to reproduce a color digitally — in CSS, in a design tool, in a presentation — RGB values are the most direct specification you can use for screen-based applications.
Getting RGB from a physical color
The app bridges the physical and digital worlds: point your camera at any physical surface — a wall, a fabric, a product, a natural object — tap the color, and you get its RGB values in sRGB color space. This is how a graphic designer pulls a brand color from a printed swatch to use in digital work, or how an interior designer translates a wall color into a digital mood board.
RGB values from the camera are in the sRGB color space, which is the standard for web and screen work. If you need the color in a wider gamut (Display P3, Adobe RGB), the app notes when a color is outside the sRGB gamut.
All color formats together
The same tap returns RGB values alongside hex code, HSL, HSB, CMYK, and the nearest paint brand matches. Each format serves a different workflow: RGB and hex for screen design, CMYK for print work, HSL for CSS and design tool color pickers, paint matches for physical color specification.
Having all formats in a single panel eliminates the need for color conversion calculators and ensures consistency — all values are derived from the same single sample rather than converted through lossy approximations.
Using RGB values in design tools
Copy the R, G, and B values separately or copy the full CSS rgb() function syntax (e.g., rgb(74, 124, 139)) with one tap. In Figma, Sketch, and Adobe XD, you can paste this directly into the color input field. In CSS, the value is ready to use in a style declaration immediately.
For Tailwind CSS users, the app also calculates the nearest Tailwind color class from the sampled color — useful for staying within a design system while incorporating real-world color inspiration.
