How to Mix Two Colors With a Color Mixer

Enter two supported color values, choose a ratio from 0 to 1, and start the calculation. When both inputs parse successfully, Color Mixer returns mixed, multiply, and screen hexadecimal values together with an RGB-formatted mixed value.

What this color tool provides

Use Color Mixer when you want to combine two color values and compare several blend results at one ratio. It accepts hash-prefixed hexadecimal text, including three-digit text such as #0f0, or text containing an rgb(...) pattern with three nonnegative integer channels. Color text is trimmed and lowercased before the parser attempts to read it.

The ratio describes how the result moves from the first color toward the second. A value of 0 keeps the interpolation at the first color, 1 reaches the second, and a value between those endpoints places each channel between the corresponding input channels. A successful calculation provides mixed, multiply, and screen results as lowercase six-digit hexadecimal values, together with an RGB-formatted mixed value.

This makes the tool useful for comparing different ways to combine the same pair rather than treating one output as the only possible choice. You can start with the supplied defaults, enter your own supported values, or change the ratio to examine how the balance shifts between the inputs.

Enter values and run a calculation

1. Enter the first color in the first color field. Use hash-prefixed hexadecimal text, including a three-digit value, or text containing an rgb(... For a clear starting point, enter#ff0000`.

2. Enter the second color in the second color field. The value #0000ff provides a blue counterpart for the red example. When a color is omitted, the first input defaults to #ff0000 and the second input defaults to #0000ff.

3. Set the ratio from 0 to 1. Choose 0.5 for an even channel interpolation, use a value nearer 0 for greater influence from the first input, or use a value nearer 1 for greater influence from the second. After both colors parse, the tool converts the ratio to a number and constrains it to that inclusive range. If conversion raises a value or type error, the ratio resets to 0.5.

4. Start the calculation with the available calculate control. With two parsed colors, inspect the mixed hexadecimal value, the multiply hexadecimal value, the screen hexadecimal value, and the RGB-formatted mixed value. Compare these outputs while keeping the same inputs and ratio if you want to see how the calculation styles differ.

5. If the result shows an error indication instead of calculated color values, inspect both color entries before changing the ratio. An unrecognized input follows the invalid-input branch. Replace it with supported hexadecimal text or text containing an rgb(...) pattern with three nonnegative integer channels, then run the calculation again. Malformed hash-prefixed hexadecimal text can instead fail during hexadecimal conversion, so correcting that text is the appropriate next action.

Read the returned color values

Read the mixed value as the channel interpolation between the first and second colors at the selected ratio. The result is determined channel by channel, so changing the ratio changes the relative contribution of the two supplied values. The multiply and screen values come from separate calculations and can therefore differ from the mixed value.

Successful hexadecimal outputs use lowercase six-digit notation. The mixed result also appears in RGB form, which gives you another way to inspect the same mixed calculation. Output channel values are rounded, and hexadecimal channels are additionally limited to the range from 0 through 255.

An error indication means that at least one color parser did not return a usable color value for that attempt. The documented input boundary does not include named colors or unspecified color syntaxes. Malformed hash-prefixed text has a separate parsing risk, so check the characters and structure of that entry before spending time adjusting the ratio.

After comparing the three hexadecimal results, choose the output that matches the blend calculation you want to examine. If the color will be used as a foreground or background, a contrast checker can be a useful follow-up for assessing that pairing.

Worked example

You want to compare an even red-and-blue blend with the tool's alternate blend results.

Enter #ff0000 as the first color, #0000ff as the second color, set the ratio to 0.5, and run the calculation.

The result includes lowercase six-digit hexadecimal values for mixed, multiply, and screen, plus an RGB-formatted mixed value.

Limitations

• The documented input boundary covers hash-prefixed hexadecimal text and text containing an `rgb(... An unrecognized input produces an error indication, while malformed hash-prefixed text can fail during parsing.

Common errors

• A named color or malformed hash-prefixed hexadecimal value can prevent the intended parsing path. Replace it with valid hash-prefixed hexadecimal text or text containing an rgb(...) pattern with three nonnegative integer channels, then calculate again.

FAQ

What happens if I leave the fields blank?

When both color fields are omitted, the first input uses #ff0000 and the second uses #0000ff; an omitted ratio uses 0.5. Supplying one value replaces its corresponding default while the other omitted color keeps its own default.

Which color formats can I enter?

Use hash-prefixed hexadecimal text, including three-digit hexadecimal text, or text containing an `rgb(... Named colors fall outside the documented input boundary, so enter one of those supported forms instead.

How does the ratio affect the result?

After both inputs parse successfully, the ratio is constrained between 0 and 1; zero keeps the first color's direction and one reaches the second. A value or type conversion error resets the ratio to 0.5 before the calculation continues.
