    To create single-color areas, the flood fill tool is often the easiest tool. First select an odd color (e.g. pink if there is no pink in the image) and experiment to find the right tolerance setting. Undo each time. Now you pick a main area color (try control-click while flood-fill is activated) and fill by clicking into each contiguous area.

  3. Blend modes - Wikipedia

    en.wikipedia.org/wiki/Blend_modes

    The Screen blend mode inverts both layers, multiplies them, and then inverts that result. The Color Dodge blend mode divides the bottom layer by the inverted top layer. This lightens the bottom layer depending on the value of the top layer: the brighter the top layer, the more its color affects the bottom layer.

    [1] A number of vector graphics editors exist for various platforms. Potential users of these editors will make a comparison of vector graphics editors based on factors such as the availability for the user's platform, the software license, the feature set, the merits of the user interface (UI) and the focus of the program.

  5. Color balance - Wikipedia

    en.wikipedia.org/wiki/Color_balance

    Color constancy is, in turn, related to chromatic adaptation. Conceptually, color balancing consists of two steps: first, determining the illuminant under which an image was captured; and second, scaling the components (e.g., R, G, and B) of the image or otherwise transforming the components so they conform to the viewing illuminant.

  6. Color management - Wikipedia

    The type of color profile that is typically used is called an ICC profile. A cross-platform view of color management is the use of an ICC-compatible color management system. The International Color Consortium (ICC) is an industry consortium that has defined: an open standard for a Color Matching Module (CMM) at the OS level; color profiles for:

  7. Grayscale - Wikipedia

    Here is an example of color channel splitting of a full RGB color image. The column at left shows the isolated color channels in natural colors, while at right there are their grayscale equivalences: Composition of RGB from three grayscale images. The reverse is also possible: to build a full-color image from their separate grayscale channels.

  8. Color correction - Wikipedia

    en.wikipedia.org/wiki/Color_correction

    Color correction is a process used in stage lighting, photography, television, cinematography, and other disciplines, which uses color gels, or filters, to alter the overall color of the light. Typically the light color is measured on a scale known as color temperature , as well as along a green – magenta axis orthogonal to the color ...
