[Qgis-user] Extracting colours from a vector file

[Alexei Schwab]

Hi Grant,

Not sure if this is what you mean but if you want to get the colour of a feature's symbol you can use @symbol_color in the expression builder.

So adding a "colour" column to your attributes and using field calculator to set the expression to @symbol_color will give you the colour for each feature. 

It will give you a hex colour code. 

If you need the RGB values, you can use  the expression:

colour_part(@symbol_color, 'red'), colour_part(@symbol_color, 'green'), colour_part(@symbol_color, 'blue')

Regards,

Alexei
