What are the advantages and disadvantages of color QR code?
Fast response code (QR) is a barcode type that can be scanned to information or directs to a web. Most of them are black and white, even if you can create a color QR code. One of the problems with the color QR code is that poorly selected colors can create an unreadable code. If too many colors are used, then people may feel that the code is unpleasant and will not want to scan it. Most QR codes are in black and white, so the others can excel in color and businesses known by certain colors can use it to increase branding and recognition. Otherwise, the QR code may not be picked up by a mobile phone or other device. For example, if the background is dark with a dark foreground, the device may not be able to recognize the information elements and ignore the QR code. The same occurs when the background and foreground are light. There should be a contrast, either with a light background and a dark foreground or a dark background and a light foreground.
Most people who create a color QR code are used using one or two colors, and this usually warns people. The use of three, four or more colors can become unpleasant and some people can refuse to scan the QR code. It can also make it difficult to look at the QR code, which can reduce people's interest in scanning code.
Most QR codes are black and white and in a quick way to stand out on this market is to create a color QR code. If the colors are properly balanced and pleasant to see, people may quickly notice QR code and are immediately interested in scanning. If the QR code is located around other QR color codes, this effect may be reduced if the user code is distinguished from the colors used used.
Some businesses are recognized by the color of their logo or marketing, and this can be used to build branding and recognition. For example, if a company is known for using purple and gold and these colors are used in QR code, there may be someone who likes to do wellST, more willing to scan the code. This is rarely a problem for good marketing, but if the colors do not look good side by side, this effect may be reduced.
