Colors
RGB Model
- Every color can be represented by a combination of RED, GREEN and BLUE.
- Each of the 3 base colors can take a value between 0 and 255, which leads to 16.8 million different colors.
Defining colors in CSS
- RGB/RGBA Notation
- Regular RGB Model rgb(0, 255, 255) rgb(244, 179, 63)
- RGB with transparency("alpha") rgba(0, 255, 255, 0.3) rgba(244, 179, 63, 0.7)
- Hexadecimal Notation
- instead of using a scale from 0 to 255, we go from 0 to ff (255 in hexadecimal numbers) #00ffff
- shorthand, when all colors are identical pairs #0ff
SHADES of GREY
- When colors in all 3 channels are the same, we get a grey color
- There are 256 pure greys to choose from
- two examples of them are rgb(69, 69, 69), #444444, #444 rgb(183, 183, 183), #b7b7b7
