I feel like I'm somewhat color blind at times. I'm redecorating my living room and I cannot for the life of me figure out how to pair colors. I'm going for a coastal, neutral calming vibe with a hint of nancy meyers. I love blue, it needs to be my main accent colour. I'm planning on painting my walls a light sand color, not entirely beige but not entirely white. I'm trying to figure out what color to go for on my new couch, sand beige or a greige. Will a sand beige couch work with the coastal/nancy meyers vibe? I have such a hard time figuring out which colors clash despite reading all about color theory.
