User customizable tracking line color

[AgroGPS]

When tracking the line, the tracking (digitized) line always get another colour and in case of bright colours, it can't be see quite good especially on sunny day :( Why it doesn't have the colour of the layer or colour of the selected feature as it works on desktop?

This has been accepted as an enhancement request. Good job :+1: Enhancement requests are very valuable to make QField better. They sometimes attract others and just happen magically. More often however they need someone to jump in and make them come true.

@AgroGPS , this PR (https://github.com/opengisch/QField/pull/3247) has tweaked the random color generation of the tracking line to insure that we never pick an overlight bright color. It's not a user customizable color, but it should avoid the issue you've described in you filing.
