48 03 15 # Red Green Blue Digital Color • RGB to HEX
Color Pixels • Each pixel composed red, green and blue phosphers with black mask. • Each channel of the RGB has brightness levels between 0 to 255. • Total number of possible colors is 256*256*256 = 16,777,216 • The human eye blends RGB pixels into range of other colors depending on the light.
Color Saturation • Color Saturation is how bright or dull the color is • Color Saturation on the computer is controlled by the intensity of the electrons firing in the RGB filters. • High intensity means more light coming through the color phosphers which makes the screen color brighter • Lower intensity means less light coming through the color phosphers which makes the screen color duller.
The Way it Works • All phosphors without electrons firing gives black color • All phosphors with full electron intensity gives white • All phosphors equal amount electrons at lower intensity gives gray Pixel
The Way it Works • All red phosphors gives red color at high intensity • All green phosphors at high intensity gives green • All blue phosphors at high intensity gives blue Pixel
The Way it Works • Green & red at high intensity display yellow • Green & blue at high intensity display cyan • Blue & red at high intensity display magenta Pixel
The Way it Works Different brightness level RGB combos create different pixel colors • Green at lower intensity & red at higher intensity can create orange • Green at lower intensity & red at higher & blue at higher intensity can create pink • Green at higher intensity, blue at higher intensity & red at lower intensity can create light blue Pixel
Decimal System 1 2 3 4 5 6 7 8 9 • Based on human anatomy (fingers & toes) - base of 10 • Any number combo can be made by adding on another number
Hexadecimal Color System • Base 16 number system • Last 6 numbers represented by letters 1 2 3 4 5 6 7 8 9 A B C D E F
Decimal - Hexadecimal RGB is in decimal form – Web color in hexadecimal form Decimal Hexadecimal Decimal Hexadecimal 0 is the first number of both systems 0=00 255=FF
RGB to Hex • Brightness levels of pixels - 0 to 255 (RGB) • In web, Hex color system describes the color levels of the pixel • 00=0, FF=255
How it Works = 00 00 00 = FF FF FF = 99 99 99 RGB Neutral Colors in Hex Code form Pixel
How it Works = FF 00 00 = 00 00 FF = 00 00 FF RGB Primary Colors in Hex Code form Pixel
How it Works = FF FF 00 = 00 FF FF = FF 00 FF RGB Secondary Colors in Hex Code form Pixel
Hex Color Manipulation • Hex code shorthand - #369 also means #336699 • When number pairs are farther apart, color changes significantly in saturation -#376696 • When the numbers are closer together – color results are more neutral in brightness tone - #373046
Examples of wide number spread in the pairs #663796 #669637 #376696 Examples of narrow number spread in the pairs #303846 #383046 #304638
