There are two simple ways of marking a nest to help bees find their nesting tunnel- with colour and design.

Design need to be kept simple and not complex. Complex designs will likely not help bees find their homes.
Use one letter across the face of a nest. If it looks a little bare- add a coloured dot above the V and below to O for example. Simple designs consist of letters/numbers such as:
V O T L 7
No design is ok too, but increased searching time for their nest, decreases foraging time for provisions and egg laying time.
