Figura 15.17. GIMP Color Selector

Con el selector de color de GIMP, selecciona un color pulsando sobre la tira unidimensional situada en el borde derecho y después en el área bidimensional situada a la izquierda. La tira unidimensional puede codificar cualquiera de los parámetros H, S, V, R, G o B, determinado por el botón adjunto presionado. El área bidimensional codifica los parámetros de los dos colores complementarios.

Figura 15.18. CMYK Color Selector

You get to this selector by clicking on the CMYK icon. The CMYK view gives you the possibility to manage colors from the CMYK color model. If a CMYK profile is attached to the image, the profile will be used to determine the CMYK colors. See Soft-Proof Profile for more information. Otherwise, a "naive" color conversion will be performed.

Figura 15.19. Selector de color de acuarela

This selector is a little different than the other models. The principle consists in changing the current foreground color by clicking in the rectangular palette. If the current foreground color is for example white, then it turns reddish by clicking in the red color area. Repeated clicking strengthens the effect. With the slider, which is next to the color palette, you can set the color quantity per mouse click. The higher the sliding control is, the more color is taken up per click.

Figura 15.20. Wheel Color Selector

This selector uses the HSV color model. Click in the chromatic circle and drag the mouse pointer to select the Hue. Click-and-drag in the triangle to vary the Saturation (vertically) and Value (horizontally).

Figura 15.21. Selector de paleta de color

This color selector brings up a list of the colors from the current palette in the Palettes dialog. You can set GIMP's foreground or background colors by clicking on colors in the colors display. You can also use the arrow keys to move within the list of colors.

Figura 15.22. Scales Color Selector

This selector displays a global view of the R, G, B channels and either the H, S, V or L, c, h values, placed in sliders. The numbers can be represented as 0 to 255 or 0.0 to 100.0 ranges.

The symbol consisting of two arrows allows you to exchange the foreground and background color. At the bottom left of this icon, below the foreground color block, you find a switching surface with two small, one black and the other white, partially overlapping squares. If you click on these, the front and background color are reset to black and white respectively.

The Color Dialog color picker has a completely different behavior than the color picker tool. Instead of picking the colors from the active image, you're able to pick colors from the entire screen.

La desventaja es que obtiene colores después de ser procesados por la pila de colores del sistema completo, en particular la gestión del color. Significa que los valores de color resultantes pueden terminar siendo diferentes de los devueltos por la Herramienta recoge-color al elegir sobre el lienzo. Depende del usuario tomar una decisión informada sobre qué selector de color utilizar.

This is a text field with six characters. See HTML notation. You can also use the CSS keywords; enter the first letter of a color to get a list of colors with their keyword:

Right-clicking in the HTML Notation text box opens a context menu that allows you to edit your notation, particularly to paste a complex notation you have copied elsewhere.

Twelve buttons at the bottom show the last used colors. You may choose a color by clicking on one of these buttons or add the current foreground or background color to this history list.
