RGB is the color model for logos shown on screens: websites, apps, social media, email signatures, presentations and video. A digital logo palette defines each brand color as a mix of red, green and blue light, usually written as three channel values or as an equivalent hex code. Those values describe on-screen color. They are not a reliable specification for print, which normally uses separate CMYK or spot-color values.

What RGB means for a logo palette

RGB is an additive model. Screens produce color by combining red, green and blue light, and more light moves the result toward white. In standard 8-bit notation, each channel runs from 0 to 255. That gives 256 × 256 × 256, or 16,777,216, possible combinations. Black is 0, 0, 0 and white is 255, 255, 255.

A hex code is the same RGB value written in base 16. Each pair of characters represents one channel, in the order red, green, blue. For example, rgb(255, 0, 0) and #FF0000 describe the same pure red. A palette that lists both formats is listing one color twice, not two colors.

Notation | Example | Typical use
RGB channel values | 255, 0, 0 | Design software color pickers, brand guidelines
Hex code | #FF0000 | Websites, CSS, SVG files, many web tools
CSS rgb() function | rgb(255, 0, 0) | Stylesheets and inline SVG styling

Why the color space matters as well as the numbers

An RGB value only describes an exact color when it is tied to a color space. For web and general screen use, the common default is sRGB, and browsers treat untagged web colors as sRGB. Some design applications also offer wider-gamut spaces, such as Display P3. If a logo palette is defined in one space and displayed in another, the same numbers can look different.

Monitors also vary in calibration and gamut, so an RGB logo will not look identical on every screen. RGB values ensure the same instructions reach every device. They do not ensure every device displays those instructions the same way.

How RGB colors are stored in vector logo files

In vector artwork, color is an attribute of shapes. A fill or stroke on a path holds a color value, so changing that value recolors the shape without affecting its geometry. In SVG, this usually appears as a hex code or rgb() value in a fill or stroke attribute or in a style rule.

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 100 100">
  <circle cx="50" cy="50" r="40" fill="#1A73E8"/>
  <path d="M30 50 L70 50" stroke="rgb(255, 255, 255)" stroke-width="6"/>
</svg>

Not every element in a vector-format file behaves this way. An SVG, EPS, AI or PDF can contain an embedded raster image, such as a pasted photo or a traced bitmap that was never converted to paths. Those pixels carry their own color data, and editing palette values will not recolor them. A file extension alone does not tell you whether the logo is built from editable paths. Open the file and inspect its structure, for example in outline view or the layers panel, before assuming each color can be edited cleanly.

Raster previews and exports, such as PNG or JPEG versions of a logo, store color per pixel. Sampling a color from one of these files with an eyedropper can return a slightly different value from the source artwork. Compression, anti-aliased edges and color-profile handling during export can all change sampled pixels. When the vector source is available, take palette values from its fills and strokes rather than from a preview image.

Working practices for an RGB logo palette

  • Set the document color mode to RGB when the primary output is screen-based, and note the intended color space, typically sRGB.
  • Record each brand color as both channel values and a hex code so developers and designers use the same reference.
  • Keep palette colors as named swatches or global colors in the vector source, so one update changes every instance.
  • Define separate print values (CMYK or spot colors) instead of relying on automatic RGB-to-CMYK conversion, because some bright on-screen colors fall outside common print gamuts.
  • Check text and icon colors against their backgrounds for contrast, using an accessibility contrast checker based on the WCAG guidelines.
  • Confirm that nothing in the logo is an embedded raster image if the palette needs to be recolored or kept consistent across file versions.

RGB compared with print color specifications

CMYK is a subtractive model for ink on paper, and spot-color systems specify premixed inks. RGB and CMYK gamuts overlap without matching, so conversion between them is approximate and depends on the profiles used. A complete logo palette usually lists screen values and print values side by side. Each set is chosen for its medium, rather than one being calculated from the other at export time.

Reading RGB values from a downloaded logo is a technical step, not a grant of rights. Being allowed to download a logo file does not by itself allow you to modify the artwork, reuse its fonts or use the mark in a way that implies association with its owner. Check the brand's guidelines or license terms before you recolor or adapt someone else's logo.

What this overview does not cover

No specific logo, brand palette, software version or measured color values were provided for this article. It therefore gives no recommended brand colors, no exact conversion results between RGB and CMYK, and no device-specific display data. Those details depend on the actual artwork, the color profiles in use and the target output.
