Key:roof:colour

The colour of the roof of a building or building part.

Mostly used for 3D building visualization. Note, that the interpretation of colour names differs between different 3D rendering applications.

It should be used together with the building=* or building:part=* tag.

Tagging

• The colour should be given in hexadecimal, preceded by a # sign, e.g. #FFFFFF.
• You can use a descriptive name for the basic colours, e.g. white, red. However, the interpretation of the colour given in this form may vary among different 3D renderers.

Tips

• It is not always easy to choose a colour from a photo. Photos are of varying quality and colours can look different in different photos.

Colour differences of the same building in different photos

Colour differences of the same building at different hours

Early in the morning (too much yellow colour)	Sunny noon (too strong contrasts)	Late morning, light overcast

• Beware of optical illusions – a colour in contrast with other colours can look different than it does on its own. Examples:

Both the yellow dots and the backgrounds of the fields on which they are located have identical colours.

The two small squares are exactly the same colour, but the right one looks darker.

• Instead of this tag, you can use building:material=*, based on which 3D renderers often assign a colour.
