Lene,
It will depend on your attributes and how you have set it up, but, under
*Layer Properties*, *Style* the colours can be set using the *Data
defined override* option (Form Icon) Click on this and select Edit, from
her you can create the variables you want. On the right you will see a
group called Colour, depending on how you specify your colour will
depend on how you use this. For example say you have RGB values in three
diferent columns, select *Colour* and then *colour_rgb* this will add
*color_rgba(* to your expression, then using *Fields and Values*, select
the appropriate Red, Green and Blue attributes from the table and close
the brackets you should have something like *color_rgba("red", "green",
"blue") *you will know it has worked, as the *Output Preview *on the
bottom left will display the RGB value.
Similarly, if you have a single column for your RGB (formatted
correctly) the same formula would be used, buy you would have a single
field (column) in the expression.
Hope this is clear!
Regards,
Richard.

Hi,
Looking for a tutorial for colorizing with values from the attribute
table.
I have the RGB values, but can´t find a way to use it…
Forund this old one – but the functions has changed a lot since.
