Pastel blue is a very pale blue that is redder and deeper than cloud blue and redder and duller than baby blue. Its lack of vibrancy is due to the fact that it is more saturated than its primary counterpart. This pastel, like other pastels, has a calming effect. When used in a space, it provides a light, soft, and airy feel. When most people think of pastel blue, they think of spring. While it is true that this color is ideal for spring decorating, many are surprised to find they can use the color year-round to achieve a feeling of sophistication and earthiness. To achieve this effect, pair pastel blue with cold and dark browns, dark and light grays, vibrant reds, and contrasting blues. These color combinations would look great in a living room, office, or boy's room. For a more vibrant combination, pair the pastel with coral, pale pink, mint, pale gray, and teal. This combination would bring out the jewel tones in each hue and would look best in a kitchen or living room at springtime. If you want to achieve a soft, understated effect for a baby's bedroom, pair pastel blue with gentle pinks, graphite gray, olive-yellow, warm brown, and wood tones. When paired with any of the above color combinations, pastel blue can be stunning.
