RGB

Question

How to remember RGB codes for common colours

Answer 1

Just remeber this: http://acsweb.ucsd.edu/~mtakemot/CSE3/Lab2/ColorModels_files/image001.gif
#FF0000 red
#00FF00 green
#0000FF blue
Adding a color increases brightness.
Green is the brightest, red second-brightest, blue is darkest.
Removing a color decreases brightness.
Also, removing for example blue makes the color more yellow (the opposite color on the diagram).
Adding blue makes a color less yellow.
That's all you need to mix colors in your head, at least somewhat well.

Answer 5

RGB is a mixture of red green and blue to make different colors. It contains 3 inputs , rgb(red, green,blue). Minimum input for each color is 0 and maximum is 255
Example
For red , rgb(255,0,0)
For green, rgb(0,255,0)
For red, rgb(0,0,255)
You can also mix colors to get a new color
Example for white rgb(255,255,255)
There is another one rgba red green blue alpha. The alpha is used for opacity of the color
Example rgba(255,24,95,.3) the .3 means opacity is 30%. You can use 30% instead of .3 if you want
Also it's not necessary to memorize every color you can always use different websites to choose your colour
