Cool colors, like all shades of blue, are considered tranquil colors; use blue in those spaces designated for relaxation, conversation, and reflection.
How blue depends on you. Are you bold or subdued? A tried and true test is given below.
Soft Blue, as calm as the desert sky, blue like a Periwinkle, as tender as a Robin’s Egg; it’s a color that emphasizes youth, innocence, and kindly adoration, making it a soothing color year round.
Bold Blue, as deep as the evening sky, as mysterious as the sea, as rich as a Blueberry in summer, as pretty as an Oregon hydrangea, making it excellent for conversation, relaxation, and contemplation.
How Blue?
If you are wondering which blue you are, try this: go into your closet and look at your clothes. Are the dark or soft?
Or, maybe you aren’t blue at all.
