Yes. GeraCode lets you choose the dark color (modules) and the background color. Keep enough contrast between the colors to ensure the code scans correctly.
For print, the recommended minimum size is 2 x 2 cm (0.8 x 0.8 in). To guarantee scanning on any smartphone, prefer 3 x 3 cm (1.2 x 1.2 in) or larger.
