Colors


The lower left front corner is black: all three phosphors off.
The left top front corner is pure green: green phosphor full on -- others off
The right bottom front corner is pure red: red phosphor full on -- others off
The left bottom back corner is pure blue: blue phosphor full on -- others off
The right top back corner is white: all three phosphors on.



Some editing applications allow easy assignment of any color whatever:

Others give easy access to only a few colors, but most allow you to write in the html color coding for any color.  Three two-digit numbers are combined into a six digit color designation like this

<color = "#26F3B9">
Think "RGB" for red - green - blue
The numbers in the code are hexadecimal, not decimal.
Each value runs from 0 to 255, decimal (256 possible values)
which is from 0 to FF in hexidecimal.

26  F3  B9   in hexadecimal
38  243 185  in decimal

 
<color = "#26F3B9">

Many applications do color calcualtions for you.
 
 

What is color?
Why must there be three components?
