I have been working on creating a custom .spcolor file to update our company color scheme to our Sharepoint site. I have noticed that when I try to use the Change the Look feature to change the theme to one of the default themes, it doesn't change when I hit the Try it Out link.

After researching further, I noticed that the issue only occurs with the Seattle site layout and not Oslo.

I tried to look at the Seattle masterpages and the css files associated, but didn't see anything unusual. I am a novice at Sharepoint, so maybe this is just something easy I am not finding.


  • Is your .spcolor file associated with a defined look or are you attempting to change it manually after you try the look out?

  • I created the .spcolor file with the new Color Palette tool and created a Composed Look using the seattle.master file and my new .spcolor file. However, any of the default composed looks are exhibiting the same behavior.

I found the solution. The difference between Seattle and Oslo masterpages is the CssRegistration control :

<SharePoint:CssRegistration Name="Themable/corev15.css" runat="server" EnableCssTheming="true" />

So the Seattle masterpage is missing the EnableCssTheming="true" attribute which fix everyting.
