Ceiling system having a plurality of different panels

A ceiling system for use in a building space having a plurality of walls, the ceiling system comprising:

• a grid system that extends to at least two of the plurality of walls and separates the building space into an occupiable space below the grid system and a plenum space above the grid system, the grid system having:
• a first main beam;
• a second main beam parallel to the first main beam, the first and second main beams extending longitudinally in a main beam direction;
• a first cross member that interests the first main beam at a first location and intersects the second main beam at a second location;
• and
• a second cross member that intersects the second main beam at a third location, the third location being offset from the second location along the main beam direction;
• and
• a plurality of ceiling tiles that are supported by the grid system and, with the grid system, create a barrier between the occupiable space and the plenum space;
• wherein all cross members that intersect the second main beam at the second location are on a side of the second main beam that faces the first main beam;
• and
• at least one of the first cross member and the second cross member is at an acute angle relative to the main beam direction.

• wherein one of the plurality of ceiling tiles has a non-white color on its surface that faces the occupiable space, and no color on its surface that faces the plenum space.
