Is there any way to permanently disable the WYSIWYG editor?

Those codes represent something.
Each two "digits" encode one of the RGB colors.
They use hexadecimal notation, so they go from 0 to F (0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F).
00 is the decimal zero.
F is the decimal 15.
10 is the decimal 16.
1F is the decimal 31.
FF is the decimal 255.

Each of the Red-Green-Blue colors are encoded in 8 bits which span, in decimal, from 0 to 255, or in hexadecimal, from 0 to FF.

The first set of two hex digits refers to the Red color, the second set refers to the green and the rightmost set is for blue.
FF0000 gives you red
Anything else in those FF, like D40000, we'll give you a darker red.
00FF00 will give you green.
0000FF will give you blue.

Then you just need to mix and match.
Green and blue give you cyan, right? 00FFFF.
Red and green go for yellow tones. FFFF00.
Red and blue? Magenta.

Curious how these mixes are the primary colors used on printers.

Last, but not least, FFFFFF is white.

So is this industry standard or peculiar to this software?
