Can anyone tell me how or point me to a tutorial to teach me how to change the colour of the line in pinch draw or change brush size, or change any sort of drawing attribute with gestures please, thank you.

You will need to modify the PinchDraw script. The color of the line is set by the Material property of the script. To change the color, you will need to dynamically modify the material's properties. This is a little bit tricky in Unity, I think the best way to change the color in this scenario is using a MaterialPropertyBlock, but I could be wrong. Since a line segment only has a single material, you probably also want to finish the current line and begin a new line when you change colors. The PinchDraw class has functions for that.

In the DetectionExamples module that contains the PinchDraw script, you will also find an example scene named PinchDrawDemo that uses the script. In this case, the PinchDraw script is just on an empty game object. The transform of that object isn't used.

okay i figured it out, i had to comment out the 'serialize field' part of the code, and just changed the color by using 'Color,red' etc.
