That is commonly why coloured paint is used.
yes objects painted black dry faster than those painted white because the black absorbs more heat than the white
No, automotive paints do not oxidize as older ones did.Today's paint's are mostly basecoat clearcoat's to protected the colors from fading or oxidizing.But some colors like red's and the weather and so on facter in this. True the oxidation factor is lessen with the newer acrylic paints, however paint, as in all things will still oxidize. Black, Blue, Maroon and other darker colors are most visibly effected. Wax only covers up the problem and polish will wear the finish away. Acrylic Paint Conditioners remove and prevent oxidation on acrylic paint.
Yes
Red is one of the three primary colors, the other two being blue and yellow. This means that colors cannot be mixed to create red, red is mixed with the other primary colors to create other colors, secondary and tertiary colors.
short answer;The three primary colors are red, yellow, and blue; they are the only colors that cannot be made by mixing two other colors.
The flags or other objects are colored with paints, dyes, etc. !
Reflects, other wavelengths (colours) are absorbed
The color of an object is determined by the color/s that it reflects. All other colors are absorbed. White objects reflect all colors, and black objects do not reflect any colors.
Poster colors are also called Tempra paints. They are water based paints and are simple to use. The way to use them is to mix them with water until they are a thick consistency. Then take a brush and use a poster board or other surface to paint on and paint away.
Octopus communicate with each other by the movement of their body and the change of body colors.
Yes, though sometimes they change the color of light, or more accurately they allow a certain color to pass through and block other colors.
This applies not only to opaque objects. The basic idea is that white light is a mixture of different colors, and objects tend to reflect the different colors - the components of white light - in different proportions. For example, an object that reflects most of the red light but not much of the other colors will look red.
Studies have shown that they dont dry out nearly as fast as other paints.
White!- at least in light. If you do this with paints you'll most likely end up with brown because mixing all the primary colors produces brown.
Doppler shift
It depends on the medium, but white light contains all colors of the spectrum. As does the black appearance of solid objects.
because the object absorbs all the other colors and reflects white
