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.

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
