In the lower left image, drawing a blue star on a green background causes the Apple II to add black, white and orange pixels at and near the horizontal boundaries between the green and blue. When the Apple II came out, a new mode had been added for 280×192 high-resolution graphics.
In the high-resolution 640 × 200 mode (Mode 6), each pixel is one bit, providing two colors which can be chosen from the 16-color palette by programming hardware registers. In this mode, the video picture is stored as a simple bitmap, with one bit per pixel setting the color to "foreground" or "background".
The background figure is the CIE xy chromaticity diagram. The choice of primary colors is related to the physiology of the human eye ; good primaries are stimuli that maximize the difference between the responses of the cone cells of the human retina to light of different wavelengths , and that thereby make a large color triangle .

In digital imaging, a pixel (abbreviated px), pel, [1] or picture element [2] is the smallest addressable element in a raster image, or the smallest addressable element in a dot matrix display device.
The two colours of a character cell are called the foreground colour and the background colour. For any value of n from 0 to 7, the following Sinclair BASIC commands can be used to set or alter the colours of a cell: [15] PAPER n, the background colour for the character cell; applied to all pixels of value 0 in the cell
