Problems with colors defined as variables for "fill" property

[PiotrSss]

For example:

:root {
    --el-clr: #000;
}
.el {
    fill: var(--el-clr);
}

generates error: var(--el-clr) is not a valid color 3 or 6 hexadecimals numbers : var(--el-clr)

Indeed, all css3 properties were updated, but not all SVG ones yet

closing issue as it is fixed for fill, but work will happen for other SVG properties.

Thank you!

As a followup, now done via #337

@ylafon I still see the same error for variables with a default value: fill: rgba(var(--color-rgb, '0,0,0'), 0.3);

This one is parsed as rgba(, ) instead of rgba(, , , ) need to check how to interpret this.
