Move one color between the notations your work uses

HEX and RGB are two notations for the same sRGB channels, not two different colors. Edit any accepted field and the preview plus every output row follow that color.

Choose the output by where it will be pasted, whether it needs opacity, and whether the text remains readable against the finished background.

Six HEX digits hold three channels

In #RRGGBB, each pair is a hexadecimal value for red, green, or blue. RGB writes those same channel values as decimals from 0 to 255.

Start with the notation you have

Paste a design token into the HEX field or enter numeric channels in RGB. The # is optional, and a shorthand such as #f80 expands to a six-digit color.

Alpha is opacity, not another color channel

At 100% the color is opaque; at 0% it is invisible. The RGB channels stay the same, but the surface behind a transparent color changes what people see.

Let the destination choose the output

Use HEX or RGB for an opaque color. Use HEXA or RGBA when opacity belongs in the value. HSL and HSV help inspect hue and saturation; use the CSS row when a declaration is needed.

The white and black ratios are a first check

The contrast cards compare the current background with white and black text. They do not replace checking the actual font size, weight, image background, or surrounding colors.

Harmony swatches begin with the current hue

Complementary colors sit opposite, analogous colors sit nearby, and triadic colors are spaced around the hue wheel. Treat a swatch as a starting point, then inspect the pair in context.

Read #FF8800 as RGB

#FF8800 becomes rgb(255, 136, 0): full red, some green, and no blue. That combination produces an orange family color.

Add 50% Alpha to the orange

With #FF8800 and Alpha at 50%, RGBA is rgba(255, 136, 0, 0.50) and HEXA is #FF880080. Its apparent color depends on what sits behind it.

Recent colors stay with this browser

The history helps revisit colors selected in the current browser. It is not an account-based list and does not automatically travel to another browser or device.

Check the string before pasting

Confirm the channel range, opacity, punctuation, destination syntax, and real background. A valid conversion alone does not prove a final interface is readable.

Choose an output format

  • HEX: a six-digit opaque color code
  • HEXA: an eight-digit HEX code with Alpha
  • RGB and RGBA: decimal channel functions
  • HSL and HSV: hue-based ways to inspect a color
  • CSS: a copyable declaration

Check alongside a contrast ratio

  • Whether text is normal or large
  • The actual text weight and color
  • Images, gradients, or patterned surfaces
  • Any transparency layered over another color

Keep inputs in range

  • HEX accepts # or no # and three-digit shorthand
  • Each RGB channel runs from 0 to 255
  • Alpha runs from 0% to 100%
  • Use Alpha 100% when no transparency is intended

Questions about color-code conversion

Do I need to include # in a HEX code?

No. The tool accepts #FF8800 and FF8800. It also accepts a three-digit shorthand such as #f80 and normalizes the result to six-digit HEX.

What does Alpha 50% copy as?

For #FF8800 at 50% Alpha, RGBA is rgba(255, 136, 0, 0.50) and HEXA is #FF880080.

Should I use HEXA or RGBA?

Use the syntax accepted by the destination. Both carry color and Alpha, but HEXA is eight-digit HEX while RGBA is functional notation.

Are HSL and HSV different colors from RGB?

No. They describe the same displayed color through hue, saturation, and lightness or value.

Can a contrast ratio alone prove accessibility?

No. This tool shows white and black text ratios. Check the actual font size, weight, background, and use context as well.

Do recent colors appear on another device?

No. Recent colors are stored in the current browser and are not automatically synchronized to another browser or device.

Color syntax and contrast thresholds are described by public specifications. Check which syntax the destination supports.
