HTML COLOURS (python?)

[matmatmat]

I have these colours:


#000
#FFEBCD
#fff
#56554e
#ffffff
#fff
#888
#FFEBCD
#888
#FFEBCD

are they HTML colours and, if so, does anyone know where I can get a list of all HTML colours (in some format that will be easy to put in a list)?
Thanks in advanced

There are ~ 16.8 million different "HTML colours". You don't want to put them all in a list.

Basically, everything is a HTML colour which starts with a "#" and then has 1-6 hexadecimal digits in it (which are 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,and F, provided that you convert the string to upper-case beforehand). Leading Zeros might be missing, so "#fff" should be equivalent to "#000fff".

EDIT: If you want to have a list of "common colours", look here: http://en.wikipedia.org/wiki/X11_color_names

Thanks for the reply, which ones should I put in & is there a way to sort the fff problem?

This is not really a problem. If your application just outputs these codes, just output only 6 digit codes. For reading code, reformat them to fit into the 6-digit scheme.

I've already linked to a colour list in my last post.

I'm wanting to check if the codes (which will be read from a file) are valid.

Then check if the first character is a "#" and the other characters are hexadecimal digits and that the number of digits is >= 1 and <= 6 (good HTML pages should only have 6-digit numbers). Note that there are also some colour names that can be used instead of these codes. Google them up if you need them.

Huh? #-o

I thought #FFF equated to #FFFFFF, #000 to #000000, etc.

^#[a-zA-Z0-9]{6}$

try:
int(color_code, 16)
except ValueError:
return False
else:
return True


Be sure to remove the '#' in color_code before hand.

6 hexadecimal digit code:

#rrggbb

And actually, the other 3-digit codes:

#rgb

Example 1 (6-digit):

#FA00C9

FA = 250
00 = 0
C9 = 201


Example 2 (3-digit):

#C09

C(C) = 204
0(0) = 0
9(9) = 153

Which is equivalent to #CC0099

Btw, CSS has also other valid color notations:

[<property>-]color: [<color_name> | rgb(<int>, <int>, <int>) | rgb(<r%>, <g%>, <b%>) | #<RRGGBB> | #<RGB> ]
