Document Summary
We need to know about the range (e. g. intensities) For example: redness o to 255 (about 8 bits), 0 to 1. 0. Saturation: how close is the color close to r/g/b (unit: percentage) Note: we need to know about the range. Vga (video graphics adapter) linked to ibm products. 8 bits and palettes and numbers between 0-256, they just pointed to a specific colour and did not represent a colour directly. Point out the universe is not inherently continuous. Sun/continuous arc = our perception of it vs. of whether it moves that way. Rgb encoding; not far away from our own eyesight. Light is a vibration, some wavelengths are small (closer to blue) and some are longer (closer to red) Different from sound, we don"t see all the frequency of light and if you take 2 frequencies of light you"ll get something in between until sound, you"ll hear both sounds.
