GIMP 52 color balance; hue-saturation; colorize; brightness-contrast; threshold; levels; curves; posterize; desaturate; These commands do not have designated buttons, but you can select each tool in the Colors tools menu. The Tools menu that is opened using a special list of commands through Add TabTools contains many tools without they eye icon . When you click on the eye icon that is in front of a particular tool icon, the tool selected appears in the Toolbox. Select all tools that you see in the image above. Our Toolbox is supplemented with additional tools that allow you working with colours.
53 a) Standard Toolbox b) Tools icons that you want to see in the Toolbox are marked c) Toolbox supplemented with additional colour tools Note! To see how the commands below operate in practice, you should open as contrast images as possible. COLOR BALANCE This command modifies the colour balance of shadows, undertones and light parts in an image. You can select options in a dialog box opened through ColorsColor Balance . If the Preview (A) checkbox is ticked, a small preview window (B) opens in the top right corner of the dialog box, where you can see any changes made to the options. Each tone has a complementary colour. Complementary colours are arranged on different sides of the colour circle. It is set that cyan and red, magenta and green, blue and yellow complement each other. The intensity of key colours is suppressed by intensifying their complementary colours. Undertones are prevailing in images. To adjust them, set Midtones under Select Range to Adjust. You can set colour levels using the Adjust Color Levels slider. The first slider adjusts the balance between cyan and red, the second one – between magenta and green, and the third one – between yellow and blue. The option Preserve luminosity (C) ensures that brightness set is maintained. In this case, only the colour balance changes.
