How do I choose latex paint? What's the difference between cheap and expensive?
The main differences are in environmental safety and durability. Good latex paint has: low VOC content, minimal odor, strong coverage, high scrub resistance (5000+ cycles), and doesn't yellow over time. We recommend mid to high-end products from reputable brands, especially for children's rooms and bedrooms where safety matters most.
How do I choose wall colors? Will dark colors feel too oppressive?
Consider these factors: 1) Well-lit rooms can handle darker colors; 2) Small spaces look larger with light colors; 3) For dark colors, consider painting just one accent wall; 4) View color swatches in natural light — colors appear darker on walls than on swatches. We recommend buying a sample to test before committing.
