GIMP has many ways of choosing colors like palettes, color choosers and using an eyedropper tool to choose a color on the canvas.
Colors can be chosen using hexadecimal color codes as used in HTML color selection.
GIMP has native support for indexed color and RGB color spaces, other color spaces are supported using decomposition where each channel of the new color space becomes a black and white image.
Color blending can be used by using the blend tool, by using a gradient to the surface of an image and using GIMP's color modes.
Gradients are also integrated into tools such as the brush tool, when the painter paints this way the color slowly changes.
There are a number of default gradients included with GIMP. A user can also create custom gradients with tools provided. [ Register or Signin to view external links. ]

There are many tools that can be used for editing images in GIMP. The common tools are a paint brush, pencil, airbrush, eraser and ink tools used to make new or blended pixels.
Tools like the bucket fill and blend tools are used to change large regions of space in an image and can be used to help blend images.
GIMP also has a selection of smart tools, which are tools that use a more complex to make a user to do things that otherwise would be time consuming or impossible.
These smart tools include the clone tool that copies pixels using a brush, the healing brush which copies pixels from an area and corrects the tone and color where it is being used. A list of GIMP transform tools include the align tool, move, crop, rotate, scale, shear, perspective and flit tools. [ Register or Signin to view external links. ]

An image being edited in GIMP, could include many layers. Each layer is made up of many channels.In a RGB image there are about 3 or 4 channels, each of a red, green and blue channel. Color sublayers look like a little different gray images, but when put together they make a complete image. The fourth channel that may be part of a layer is the alpha channel , this channel measures opacity where a whole or part of an image can be completely visible, partially visible or invisible.
