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

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:

Getting colours from a scheme
To get the colours for an specific scheme just clic on the name of the scheme

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
Excellent! Super!

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
