Very nice.


 Troy showed me this one:

This one isn't as nice but it does have the contrast option for a color
theme.

I was researching this subject last week and came across this:
http://jrm.cc/color-palette-generator/

You upload an image and it generates a color palette based on the colors of
the image. Seems very useful.

Googling for color theory should return some informative results on how
this is done. Still, I've seen artists do this by eye and come up with
spectacular results that make any auto-generated theme look calculated and
mathematical.

Re: [ubuntu-art] Choosing color palettes

Interesting, it appears to simply scale the image down to a 3x3px image (or
optionally 5x5, 7x7). Look at the duck or landscape 11 pictures. This
probably isn't the best technique for creating a pallet. In essence, you
could recreate the application with a bit of python code...

 import Image
 im = Image.open(attackhamster.jpg)
 print im.size
(800, 600)
 size = 3,3
 im.thumbnail(size)
 for pixel in list(im.getdata()):
... print #%02x%02x%02x % pixel
...
#030400
#030303
#060503
#030303
#070508
#fdc087
#0f1b4f
#895a3c
#936858
 colors = im.getcolors()
 colors.sort(reverse=True)
 for count,color in colors:
... print #%02x%02x%02x x%d %(color[0],color[1],color[2],count)
...
#030303 x2
#fdc087 x1
#936858 x1
#895a3c x1
#0f1b4f x1
#070508 x1
#060503 x1
#030400 x1

It would probably be better to use the 9x9 and then pick one or two colors
and use them as a base to generate a pallet from one of the other tools.

hmm... that attackhamster.jpg does produce a very nice color pallet

 This one has a selector that shifts a color scheme in the way some people
 with color perception problems will see it. Very useful.

 I think the most important use of this one is that you can generate a
 palette from a wallpaper picture. That will ensure that the wallpaper will
 fit well to the color scheme.

Rather spot on.  That said, at least understanding
how some basic colour theory works in principle to pull
out colour chords and such is probably a good starting
point for many who have zero to no experience in the
subject.  If we head further down this path, we could
potentially suggest that the work accomplished thus
far (and in the past for that matter) would do well to
have the basic principles highlighted.

The immediate value of a decent colour palette tool
is in its experimentation ability.

Colorscheme2 is the most 'by-the-book' tool I have
found so far, and it offers a good degree of flexibility
to roll the colour wheels locked in some of the more
standard approaches.

Sincerely,
TJS
