RGB to HEX
Convert RGB to HEX. See worked examples, understand the conversion method, and check practical limits before using your result. Check the format first.
RGB to HEX color conversion
Use RGB to HEX when a design specification, stylesheet, or color editor needs a different representation of the same color. Start hexadecimal input with #, or use a lowercase rgb, rgba, hsl, hsla, or hsv function name. Select Submit, then check the target-format result before copying it.
How this conversion works
Use the red, green, and blue channel values as the starting point. Normalize the color channels by dividing by 255 when a destination formula expects values between 0 and 1. For HEX output, round each 8-bit RGB channel as needed and encode it using two hexadecimal digits. Plain #RRGGBB has no alpha pair.
Worked color example
The sample rgb(51, 102, 153) corresponds to #336699 for the color coordinates illustrated here. Small differences in the final digits can result from rounding. This example explains the mathematical representation; it does not establish which input syntax this tool accepts.
Understand the formats
RGB represents red, green, and blue channels. In the 8-bit convention used by these examples, each channel runs from 0 to 255. HEX encodes red, green, and blue as hexadecimal channel pairs. For #336699, the pairs 33, 66, and 99 correspond to decimal channel values 51, 102, and 153.
Transparency and rounding
Neither example has an explicit alpha channel. This conversion changes the way color coordinates are written. If you need transparency, use an alpha-capable representation and inspect its opacity value separately.
Frequently asked questions
Will the converted color look identical everywhere?
Equivalent coordinates describe the same color within the assumed color model. Displays, color profiles, surrounding colors, and backgrounds can affect appearance. Compare the result in the application where you will use it.
Can I interchange HSL lightness and HSV value?
No. They are different calculations. Recalculate the destination coordinates instead of moving the same percentages between HSL and HSV fields.
