I have imported my customised icon (which was obtained through the .jpeg image conversion) for point layers using an SVG file.

This works well except for the fact that the original colour was replaced by black.

Under the "Symbology" menu I cannot change the colour of the "SVG marker" (see picture below).

If I try to change it in the level above under "Marker" this does not change the colour of the icon. Any ideas or suggestions?

Here is the code of my SVG (opened in Browser):

You can simply do it directly in QGIS (works both 2.18 and 3.0.3)

Layer Properties > Draw Effects > Effect Properties

Open your SVG "Layer Properties" and click "Draw Effects" and then open the Star symbol "Customize effects" .

Then use "Colorise" as an "Effect type"

• Documentation QGIS Testing | Draw effects


• Introducing QGIS live layer effects

You need to edit the SVG file and replace the

fill="#000000" stroke="none"

by something like

fill="param(fill) #FFF" stroke="param(outline) #000" stroke-width="param(outline-width) 1"

the "param(xxx)" part allow you to set the xxx parameter from the qgis interface, the #XXX part is the default color.

For a more detailled explanation see this answer How to create svg symbols that have modifiable fill color, stroke color and stroke width?

Using notepad++ (or any other decent text editor) simply change in this part

<g transform="translate(0.000000,390.000000) scale(0.100000,-0.100000)"
fill="#000000" stroke="none">

the code for "fill" to any desired color. E.g. fill="rgb(0,255,0)" for a green symbol.
