The above GIF stores the NTSC palette as an indexed image, with each colour set to the corresponding palette RGB value displayed by a NTSC '2600. In other words, the colour number in the image will show the corresponding colour displayed by the Atari. The '2600 does not use the low bit of the colour number, so we have 128 pairs of colours here.

Console Differences

"most (all?) six switch 2600's have a 680 ohm resistor between TIA pins 6 and 9, which boosts the chroma saturation. Later models omit it." - RevEng
