Paint colors and the sun's heat

Will paint color affect the room temperature especially during hot summer days?

I am thinking of painting my room either olive green or light gray.

I am asking because I heard that when wearing clothes with dark colors, they tend to absorp heat faster than light colors.

Thanks for reading.

Paint colors and the sun's heat

For an interior, and if the sun is not shining on the painted surface, there should be a neglibile difference in the temperature of a room. It will have a difference on the exterior.

Also, the interior walls are not insulated, so this evens out the interior temperarures.

Psychologically, people seen to associate dark areas with being cooler for some reason.

Dark colors absorb more radiant heat and light clors tend to reflect it.

Some colors also 'feel' warmer or cooler. Blues and greys are considered cool colors and yellows and oranges are considered hot colors.

No, not unless the sun is actually shining on the surface
But if the sun is shining on the dark surface, yes, it could be noticeable

Room temperature in summer depends more on insulation, drafts, amount of shade on house, window quality and coverings, proper sizing of HVAC and location of vents, amount of air circulation, ventilation, etc. Effects of color tend to be more psychological than physical in that they can be more tranquilizing (cool) or more energizing (warm). Of course, lighter colors are more reflective than darker colors, but other factors tend to outweigh the effects of paint color on room temperature.
