When I was little my cousin told me to remember this silly made up word to remember how many colors: ROY G BIV. Each letter is the beginning of the color in the rainbow which is 7. Red-Orange-Yellow Green Blue-Indigo-Violet. Kinda silly but it helped me remember for 30 years now.

"All the Roy G. Biv mnemonics follow the tradition of including the colour indigo between blue and violet. Newton originally (1672) named only five primary colours: red, yellow, green, blue and violet. Only later did he introduce orange and indigo, giving seven colours by analogy to the number of notes in a musical scale.[14] Some sources now omit indigo, partly due to the poor ability of humans to distinguish colours in the blue portion of the visual spectrum.[15] There is also some evidence that Newton's use of the terms blue and indigo map to the modern hues turquoise and blue respectively.[citation needed]
Since rainbows are composed of a nearly continuous spectrum, different people, most notably across different cultures[attribution needed], identify different numbers of colours in rainbows."
From what I've heard, Newton was a very religious man so he made it 7 colours because 7 is a religious number.

there are unlimited colors in a rainbow, but most people only distinguish the main 7 that are always listed, as in red orange yellow green blue indigo violet. but there are definitely more than just 7 colors, they are made up of every color in the visible spectrum

People typically refer to 7: red, orange, yellow, green, blue, indigo, violet. In reality there is an infinite number because there can be very subtle differences of shade between one and the other.
