Blue is often calm and cool, but it can also be electric. Think cobalt, sky blue, turquoise. Like my Blue Dot pattern available on Spoonflower.
These shades feel energetic rather than soothing, more joy than serenity.
Blue pairs beautifully with lemon yellow, tomato red, grassy green and buble gum pink.
The contrast gives the sense of movement.
Patterns: stripes, florals and checkard look great in blue.
