Thanks !

Good feature, I didn't know. But it wasn't what I was looking. I was looking for :

• a widget in a simple view form (no kanban, but it's ok) ;
• the possibility to choose any color (that feature doesn't allow that) ;

For your information, to do what Mariusz Mizgier said :

• In the python file (like in project/project.py) :

  _columns = { 'my_color_field': fields.integer('My Color Field'),}

• In the kanban view (like in project/project_view.xml) :

  <ul class="oe_kanban_colorpicker" data-field="my_color_field"/>

It's possible to pickup 10 different colors defined in the two following files :

• openerp-web/addons/web_kanban/static/src/js/kanban.js

number_of_color_schemes = 10

• openerp-web/addons/web_kanban/static/src/css/kanban.css

.openerp .oe_kanban_view .oe_kanban_color_0 {background-color: white;}

.openerp .oe_kanban_view .oe_kanban_color_9 {background-color: #ffc7f1;}

You should refer to class oe_kanban_colorpicker with table column color of type integer. You could easily trace how does it work using project kanban view.
