Sunlight has seven colors because the atmosphere acts as a filter, it changes the color, for instance the setting sun, looks yellow or orange.
white light is made up of all the colours so that means white light can absorb all the colours
The discovery that light is made up of seven colors was credited to Sir Isaac Newton. He demonstrated this by passing sunlight through a prism and observing the separation of the light into its component colors, creating a rainbow spectrum.
Use a prism.
When sunlight passes through a prism, it can be separated into a spectrum of seven distinct colors. These colors are red, orange, yellow, green, blue, indigo, and violet, often remembered by the acronym ROYGBIV. This phenomenon occurs due to the refraction of light, which bends different wavelengths at varying angles.
rainbows are light separated into it's 7 colours. You can only see a rainbow from one direction and the rainbow is created when the light reflects off the water thus separating it into the seven colours. You can also see rainbows sometimes when watering a garden or really anytime when there is water in the air.
The sunlight spectrum contains all the colors of the rainbow, which are typically represented as red, orange, yellow, green, blue, indigo, and violet. So, there are seven colors in the sunlight spectrum.

The sunlight hits the glass of water and then the light disperses out as a spectrum of colour (rainbow). This is because sunlight is white light and white light contains the 7 colours of the rainbow. When it hits the glass the colours refract and disperse out as the spectrum of colours, which we see as a rainbow.
Right after a thunderstorm, there will still be some water droplets in the sky. When the sunlight shines on these water droplets, the white light that is reflected off the water droplets is split into seven different colours: red, orange, yellow, green, blue, violet, indigo.

A clear glass prism is used to separate sunlight into rainbow colours.
dark colours draw sunlight/heat
White - or light colours... to reflect sunlight.
seven colours
Because "color" is an interaction between the visible light portion of the electromagnetic spectrum and the light sensitive parts of our eyes. Our eyes have evolved 4 different receptors--one each for Red, Green and Blue and another for violet. A rainbow actually contains millions of colors, but we have evolved to categorize most of the wavelengths in the visible spectrum as one of the primary colors and their combinations.
