Long Zheng, over at istartedsomething.com has conducted more experiments with the new Microsoft Tag.
In this blog post, Long has tested Tags that are not just colourul (that is: RGB/CMYK) And with great success! From Long’s tests, he states that it is reading the Brightness (not just saturation and hue) – therefore, Tags with levels of grey are possible.
Thanks for the testing, Long.
