Two-way RGB and HSB/HSV color code converter supporting multiple input formats. Ideal for designers and developers.
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
RGB describes a color with red, green, and blue channel values. In this converter, each channel ranges from 0 to 255. HSB describes the same selected color with hue, saturation, and brightness: hue is an angle from 0° through 360°, while saturation and brightness are percentages. HSB is commonly used as another name for the HSV-style model, where the third component is called value.
HEX expresses the RGB channel values in hexadecimal notation, such as #3B82F6. The tool keeps RGB, HSB, and HEX synchronized as you change the color, and accepts a color selection as well as editable values. A converted RGB color can therefore be copied into CSS or design notes while HSB values can be used when adjusting hue, vividness, or brightness.
HSB and HSL are related but not interchangeable: both use hue and saturation, while HSB brightness/value and HSL lightness use different definitions. A value from one model should not be relabeled as the other.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Use the color picker, adjust the red, green, and blue channels, or enter a supported HEX color. RGB channel controls use integer values from 0 to 255.
Hue appears in degrees; saturation and brightness appear as percentages. You can also adjust those HSB components to update the corresponding RGB and HEX values.
Use the displayed value in a design brief, stylesheet, or palette record. When sharing a color with someone using a different color model, label the values explicitly.
For example, RGB (255, 0, 0) corresponds to HEX #FF0000 and HSB (0°, 100%, 100%). Black has zero brightness; hue is not visually meaningful when saturation is zero.
Use cases
See how the tool fits into real work and everyday tasks.
A designer with RGB channel values can use the matching HEX string in a CSS declaration. Keep the leading hash when the target syntax expects a six-digit HEX color.
When a teammate asks for a more saturated or brighter version, the HSB components describe those edits directly. Share the complete triple so the recipient can reproduce the color.
Change one RGB channel and watch the corresponding hue, saturation, and brightness shift. This makes clear that all three formats are alternate descriptions of one color selection.
Q&A
Find concise answers to common questions and confusing cases.
HSB (hue, saturation, brightness) is commonly used for the HSV model, where V means value. The terms refer to the same style of representation in this tool.
They share hue and saturation labels, but the third component differs: HSB uses brightness/value, while HSL uses lightness. Their percentages are not directly interchangeable.
Hue describes a position around the color wheel. With no saturation, a color has no visible hue; black also has zero brightness. The numeric display may still contain a hue value, but it does not make those colors visibly tinted.
The six-digit HEX form with a leading # is a standard CSS color notation. Confirm whether the receiving field also accepts shorthand or alpha-channel forms before entering a different HEX length.
Notes
Review scope, result limitations, and important precautions before use.
HSB values are rounded for display, so converting rounded values back may not reproduce every original RGB channel exactly. Use the RGB or HEX output when exact channel values matter. RGB values describe encoded channel numbers; they do not by themselves communicate display calibration, a print profile, or a perceptual color difference.
