This one open space will have area for couch/tv, office/desk, and kids corner. Overall I want the room to feel warm and interesting for family entertainment but minimalist and modern. I have these pillows that have like a dark teal and mossy green colors on them that are gorgeous and wanted to use that as my inspiration. But I am very worried that these colors are too dark for the space. Do dark colors make space with no natural light smaller? Here is my idea, I am going to install white hardwood floor and paint ceiling and trimmings bright white to offset the dark paint colors. Though I am even having a hard time looking for the right teal or mossy green (that doesn't look gross). Should I scrap this idea and find something else? Is there a third color that I can use to compliment/contrast these colors? All suggestions welcome!

Behr's website has a thing where you can make palettes of different Behr paint colors, BUT, you could do that on this site as well.

For a dark basement space, I would go with light colors (pale yellow, cream, pale blue) and reflective surfaces (mirrors, metallic accents, glass) to bounce light around.
