Hi everyone,
Well, as you probably read, I was working on a Color palette. The thing is
that i loved the color schemes from www.colorbrewer2.org , so I decided
to bring them into Pharo/Moose then everyone can use them directly.
So I created ColorPalette. A color palette is a collection of different
color schemes that follows a common purpose, they are: sequential,
qualitative and diverging.
Sequential schemes are suited to ordered data that progress from low to
high.

Diverging schemes put equal emphasis on mid-range critical values and
extremes at both ends of the data range
.<Screenshot 2014-04-24 23.46.46.png>
Qualitative schemes do not imply magnitude differences between legend
classes, and hues are used to create the primary visual differences between
classes .

Picking the right scheme from a palette
You can see all the color schemes for each palette by executing
=.=.=.
ColorPalette sequential show.
ColorPalette diverging show.
ColorPalette qualitative show.
=.=.=.
You should see something like this:
<PastedGraphic-8.tiff>
Getting colours from a scheme
To get the colours for an specific scheme just clic on the name of the
scheme
<Screenshot 2014-04-24 23.53.36.png>
And you will get the code line to get them.
<PastedGraphic-7.tiff>
Example:
=.=.=.
ColorPalette qualitative colors: 7 scheme:'Accent'
=.=.=.
If you want to focus on a specific color, just click on it to inspect it.
Partitioning data into colors
With Ricardo, we were working on a new normalizer to discretize a list of
values into a smaller list of colours using Sequential or Diverging color
schemes.
Example:
=.=.=.
RTBucketColorNormalizer example
=.=.=.
What do you think?
Cheers,
Pablo

Yep. It is not completely integrated into Roassal2 Color Normalizers, I
will announce it today.
These are the palettes:

Keep in tune ;-)

Hi!
Just to say that Pablo is working on a harmonized color set for Roassal2.
He will probably announce it soon :-)
I know some of you are interested in that :-)
Cheers,
Alexandre
