Arranges the red, green, or blue channel

Obviously when you switch the slider - changes the channel that is affected by the slider on the slider to the right of the square color picker. It is easy to understand how the field is changing the value - yvette.Roga commented on July 9th 19 at 10:29

I don't need, in fact. It's the little things that the artist does not need.

But if in fact, the default choice is the component H (hue hue). In this case, the color column is the choice of shade of color, square field, you select the saturation (S, saturation, horizontal) and brightness (B, brightness, vertical) color. Accordingly, switching to component S, we in the color column select saturation, and the square box shade and brightness of color. Switching to B, the color column is selected the brightness, and on hue and saturation. This is true for the components R, G, B. Only in this case, we are already working with a color representation not as HSB (hue, saturation, brightness), and RGB (red, green, blue). That is, choosing R component, the color column is governed by the intensity of the red color components (R, red), and the square of the intensity of the blue (B, blue, horizontal) and green (G, green, vertical) color component. Consequently, choosing G or B we choose a component that will be adjusted in the color column (and the remaining two will be adjusted on a square field).
Generally speaking, since the color representation of RGB or HSB components 3, on the right it would be represented as a cube where each axis is responsible for each component. Read more you can read here: https://en.wikipedia.org/wiki/RGB_color_model (in Russian wiki painfully concisely written, so I give a link in English. wiki).

But since in this cube will work, to put it mildly, not very convenient, it is one of the components bring to the slider, and the other two already live peacefully in a two-dimensional square. - brandt_Ernser commented on July 9th 19 at 10:28
