The colors of the spectrum- in order- are:
Red
Orange
Yellow
Green
Blue
Indigo
Violet
Blue is in the bottom half- start of the upper half is Red.
The colour at the opposite end of the colour spectrum is violet.
A spectrum goes from red at the low frequency end to violet at the high frequency end.
The warm end of the visible spectrum is red, while the cool end is violet.
Blue, purple is at the extreme end of the dark colors, blue is roughly in the middle of the color spectrum
The highest frequency/shortest wavelength of visible light isthe last color you can see on the blue end of the spectrum.
A color with a wavelength of 434 nm falls within the blue-violet range of the visible spectrum. This specific wavelength is closer to the violet end of the spectrum.
Hot colors are on the red end of the spectrum. Green is on the blue end where all the cool colors hang out.
Gold absorbs and reflects certain wavelengths of light, resulting in its characteristic yellow color. Blue light has a shorter wavelength than yellow light, causing it to be absorbed rather than reflected by gold. This is why gold appears yellow and does not reflect the color blue.
The color of an electromagnetic light wave is determined by its wavelength. Shorter wavelengths correspond to colors towards the blue end of the spectrum, while longer wavelengths correspond to colors towards the red end of the spectrum.
The frequency of the wave determines the color of light. Higher frequency waves correspond to colors towards the blue end of the spectrum, while lower frequency waves correspond to colors towards the red end of the spectrum.
Wavelength determines the color of light, with shorter wavelengths corresponding to higher frequencies and colors towards the blue end of the spectrum, and longer wavelengths corresponding to lower frequencies and colors towards the red end of the spectrum.
Red , Yellow and Blue are the Primary Colours because you cannot make them from other colour pigments. Also Red colour is at the Long wave end of the Spectrum. Blue colour is at the Short wave end of the spectrum. Yellow colour is at the Mid-point of the spectrum. When mixed;- Red & Blue = Purple Red & Yellow = Orange Blue & Yellow = Green
