Sunlight has seven colors because the atmosphere acts as a filter, it changes the color, for instance the setting sun, looks yellow or orange.

Isaac Newton discovered that white light is made up of seven different colors when he passed sunlight through a glass prism.
Diamonds interact with sunlight the same way prisms interact with sunlight. You will see all the colours of the rainbow reflected by a diamond.
Because the violet dress reflects violet and absorbs the other colours.
Use a prism.
The sunlight spectrum has seven colors. The colors are: red,orange,yellow,green,blue,indigo and violet. The abbreviation for the spectrum is ROY G. BIV

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.

Seven
A clear glass prism is used to separate sunlight into rainbow colours.
The rainbow has 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.
