Blue Color

Blue Color is calming. It can be strong and steadfast or light and friendly. Almost everyone likes some shade of the color blue.


Nature of Blue:
A natural color, from the blue of the sky, blue color is a universal blue color. The cool, calming effect of blue makes time pass more quickly and it can help you sleep. Blue is a good color for bedrooms. However, too much blue could dampen spirits.


Culture of Blue:
In many diverse cultures blue is significant in religious beliefs, brings peace, or is believed to keep the bad spirits away.


Using Blue: A deep royal blue color or azure conveys richness and perhaps even a touch of superiority. Navy blue is almost black and is a bit warmer than lighter blues. Combine a light and dark blue to convey trust and truthfulness — banker's colors. Although blue is a year-round color, pastel blues, especially along with pinks and pale yellows suggest springtime while deep blue is a colder weather color. Create a conservative but sophisticated look with subtle contrast by combining light and dark shades of blue.

WHY IS WATER BLUE?

Over the years, we have often asked scientific colleagues why it is that water is blue. Common responses have included light scattering -- after all the sky is blue -- and coloration by dissolved impurities - Cu2+ has been a popular suggestion. However, the work described below demonstrates that water has an intrinsic color, and that this color has a unique origin. This intrinsic color is easy to see, and has been seen by the authors in the Caribbean and Mediterranean Seas and in Colorado mountain lakes. Because the absorption which gives water its color is in the red end of the visible spectrum, one sees blue, the complementary color of red, when observing light that has passed through several meters of water. This color of water can also be seen in snow and ice as an intense blue color scattered back from deep holes in fresh snow. Blue to bluegreen hues are also scattered back when light deeply penetrates frozen waterfalls and glaciers.


Water owes its intrinsic blueness to selective absorption in the red part of its visible spectrum. The absorbed photons promote transitions to high overtone and combination states of the nuclear motions of the molecule, i.e. to highly excited vibrations. To our knowledge the intrinsic blueness of water is the only example from nature in which color originates from vibrational transitions. Other materials owe their colors to the interaction of visible light with the electrons of the substances. Their colors may originate from resonant interactions between photons and matter such as absorption, emission, and selective reflection or from non-resonant processes such as Rayleigh scattering, interference, diffraction, or refraction, but in each case, the photons interact primarily or exclusively with electrons. The details of the mechanism by which water is vibrationally colored will be discussed in the paragraphs which follow.

These blues and gray create a dark, conservative look.


C100M75 | C80M5Y10 | C65M3Y10 | C15Y5 | M40Y75 | C100M50 | C40K100 | White
Brighten this combo of shades of blues with a dash of orange.


C100M40 | M47Y100 | C10M95Y5
Shades of the sixties with blue, orange, and pink.


M50Y100 | C100M37K15 | C25M10K4 | White
Vary the look here by using orange as the accent or the medium blue as the accent.


C60M20Y5K10 | M75Y80 | White
It's still orange and blue color but with a more subdued look. A dash of bright white keeps it from being too subdued.


M9Y45K5 | C95M80Y30K15 | C45M40Y10K5 | M80Y100
More attraction between yellow and blue (both a light and a darker blue) with a dash of orange thrown in.


C60M100 | C30M50 | C15M25 | C70M50Y25K10 | C100M85Y35K15 | C40M20Y10K5
Show your passion for purple and your bias toward blue with this cool color palette.


C35Y7K3 | C55Y10K5 | C80Y15K7 | C100Y20K20 | Y100 | M40Y35 | C40K100
Accent these blues with a dash of yellow and pink and blue color.
