[sdk] Colors should have symbolic names

[Sebastien Bacher]

[Updated description]

Reading http://developer.ubuntu.com/api/qml/sdk-14.10/Ubuntu.Components.UbuntuColors/ the documentation suggests to use e.g blue for selection ... shouldn't we rather have named colors, e.g "selectionColor"? This way, if the theme change a day we don't need to patch every single application we are shipping to change the color!

Progress update:

We've updated the colour palette with a more useful naming structure:

There is already Palette for that: http://developer.ubuntu.com/api/qml/sdk-14.10/Ubuntu.Components.Themes.Palette/

[Sebastien Bacher (seb128)]

the palette seems to have a restricted set of colors though, e.g no color for buttons

[Tim Peeters (tpeeters)]

Yes, I think we need to extend the palette (also with colors for positiveAction, negativeAction), or think of a different way to do it.

[Jouni Helminen (jounihelminen)]

These should be in the SDK now - https://developer.ubuntu.com/api/qml/sdk-14.10/Ubuntu.Components.UbuntuColors/

[Jouni Helminen (jounihelminen)]

ah, misread.

Semantic colour names would work once we have agreed on the semantics. The current palette implementation links too many things together so are working on a better alternative

[Jamie Young (jamiedawsonyoung)]

The work on the semantic naming has been done and agreed with the teams. It's in the process of being implemented. Thanks!
