There are two types of colored bulbs. Some are just regular light bulbs with a semi-transparent color coating. A blue light bulb, for instance, will transmit blue light, absorbing out red. It will transmit smaller amounts of different colored light, but to your eye the light coming from the bulb is blue.Others actually emit light a a certain color, such as a yellow street light which is a sodium-vapor lamp. Overall the color you see is the color that is being emitted or transmitted.
black
It is a white coloured crystalline substance
Red.
White dwarfs have a broad spectrum, ranging from ultraviolet to near-infrared. However, they are most prominent in the blue and ultraviolet part of the spectrum, due to their high surface temperatures.
Colourless solution. most coloured solutions contain transition metal ions
Lights are coloured by the light they emit and are additive, while pigments are coloured by the light they absorb/reflect and are subtractive.
Colours are made because rays of coloured light are absorbed into whatever object. With white, all coloured rays are reflected and none are absorbed. It's not a colour, it's actually the lack of any colour.
Black and white... but for your information, white is the colour which holds the whole colour spectrum, meaning it was really multi-coloured and really really pretty :D
Magnesium does not produce a color in the flame test because it emits ultraviolet light that is not visible to the human eye. The energy emitted by magnesium when heated is at a wavelength that is outside the visible spectrum, so it does not result in a characteristic color.
Wand coloured.
Suppose white light is incident from a extended source on a plane parallel thick film viewed in reflected system, then for any value of r, due to large thickness the values of u can be found to satisfy the condition of constructive interference for every colour in the spectrum of white light. The different coloured fringes will overlap to produce general illumination. Thus, a thick film will produce general illumination and no colour will be seen.
They don't. They produce white milk, hippos produce pink milk
Yellow
She was dark coloured.
Pink, black,brown or coloured in spots
That depends on what colour the hole is!
black
