About it
One square holds three QR codes here: the first sets each module's red, the second its green and the third its blue. So each module is one of eight colors, from white to black.
Splashery's reader splits the picture into its red, green and blue and reads each one as an ordinary code, for three times the data in the same square. An ordinary phone reader sees only gray, which comes mostly from green, so it usually reads the green code or nothing. Tap the square to pull its three codes apart and back. Type your own three texts in the Splash tab, and pick the color each code shows in when pulled apart.
