Browsing through fan decks and paint chips can be overwhelming. Start by figuring out the general color characteristics: Do you want a warm or cool shade? A neutral or a saturated shade? If you have existing furniture or art, you’ll also want to consider how the shade will compliment them. Once you have a sense of what you’re looking for, pick a few shades and get samples. Test the shades to see how they look in the room at different times of day.
Many paint companies also have tools on their websites that will let you upload a photo of your space and preview different colors on the walls. But colors can look different in real-world conditions, so you’ll still need to try it out in the space.
