Double Rainbow Barcode Poster

Geometric barcode design features two rainbows made of pairs of coloured stripes that correspond to UPC numbers. Getting my geek on, the numbers correspond to the letters in "rainbow" to make a double rainbow. Since barcodes are only 12 numbers long, I let the "r" be represented by the red start and middle stripes. The sequence starts on the left with red, orange, yellow, green, blue, indigo, and violet. Two stripes of red serve as a divider in the middle and then the colours go from violet back to red for a balanced look. The white is actually transparent, so you can change it if you like. Just click the "Customise it" button, then select a “Background Colour” in the sidebar. When you're done, click "Add to cart" to purchase your customised design.
