Gimp.color_is_perceptually_identical
Description: Reference for Gimp.color_is_perceptually_identical

### Function

# Gimpcolor_is_perceptually_identical

since: 3.0

#### Declaration [src]

    gboolean
    gimp_color_is_perceptually_identical (
      GeglColor* color1,
      GeglColor* color2
    )

#### Description [src]

Determine whether `color1` and `color2` can be considered identical to the human eyes, by computing the distance in a color space as perceptually uniform as possible.

This function will also consider any transparency channel, so that if you only want to compare the pure color, you could for instance set both color’s alpha channel to 1.0 first (possibly on duplicates of the colors if originals should not be modified), such as:

    gimp_color_set_alpha (color1, 1.0);
    gimp_color_set_alpha (color2, 1.0);
    if (gimp_color_is_perceptually_identical (color1, color2))
      {
        printf ("Both colors are identical, ignoring their alpha component");
      }

Available since: 3.0

#### Parameters

`color1`

  Type: `GeglColor`

  A `GeglColor`.

  The data is owned by the caller of the function.

`color2`

  Type: `GeglColor`

  A `GeglColor`.

  The data is owned by the caller of the function.

#### Return value

Type: `gboolean`

Whether the 2 colors can be considered the same for the human eyes.
