So going to Ikea sparked some inspiration for our basement reno next spring...
For our colors we're going with Home Depot's Behr paint. Walls will be Torchlight 290B-5 to really brighten up the dungeon of a basement. Ceilings & trim will be Vanilla Delight W-B-220, also to make things brighter. The floor, if we go with the final decision to paint instead of put in tile, will be Brown TeePee 700D-4 for a neutral color to bring things back down to earth.
In addition to the sitting/TV area, wet bar, and workshop area, we'll have a pool table/air hockey table area as well:
