There are seven colors of the rainbow which can be remembered by just using one key word. This word in ROYGBIV which is an acronym for the seven colors. ROYGBIV stands for Red, Orange, Yellow, Green, Blue, Indigo and Violet.  Numerous minerals including blackish manganese dioxide, yellow and red ochre, blue chrysocolla and products of nature including salfflower, paraffin, mango leaves, blood from insects, marigold petals are just a few examples of the natural products that are being ripped from ecosystems and harvested to produce colour. Luckily, clothing and product manufactures are beginning to work more environmentally friendly, aiming to use the most sustainable sources for colour, in order to prevent natural colour compounds from fading out of earth completely. A few sources of these stores can be found here. Here i have very colorful showcase of Photos inspired by rainbow colors for your inspiration. I hope you do like my bright collection of photos.
