You can change the background colour of the 3d viewport in the File / User Preferences / Themes panel

If that’s temporarily, for a bright daylight, click on Presets in User Prefs, Themes as suggested above and choose “Blender 24X” or “3Ds Max”.

Try this out:

1 - In the World Properties window, go to the World panel and select both Horizon and Zenith and set your preferred colors, then click on the Blend checkbox.

2 - Now go to the properties window in the 3D viewer and go to the Display panel. Toggle the World Background checkbox.

3 - Press Ctrl-U to save as the start-up filre.
