Once this gradient is applied you will see a representation of this gradient in the colour panel as well as a gradient path on the canvas. From either of the two, you can select the node where the colour is applied and change this to any colour in the colour wheel or by typing in a colour value.
By using the on-canvas linear path, you can drag this path around or rotate it to change the angle or length of the gradient. This gives you simple creative control as to where these colours are placed on the shape and how tight you want the gradient to be applied. If you want the gradient to span across the entire shape, simply move this on-canvas path from one end of the shape to the other.
For more creative options, you’re not just limited on graduating colours from one colour to another. We can add many colours in between to really dial in the look we want. To do this, simply click anywhere on the path in the canvas or the gradient path in the colour panel. This will add a new colour control in that area that you can change using the same colour panel.
