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. <Screenshot 2014-04-24 23.45.43.png> 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 . <Screenshot 2014-04-24 23.46.20.png> 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 > On Apr 24, 2014, at 11:33, Alexandre Bergel &lt;alexandre.bergel(a)me.com&gt; wrote: > > Excellent!
