Please look at this sample gradient image I did with a Paint program:

![enter image description here](https://i.stack.imgur.com/F1t5l.png)

It contains 2 vertical gradients.

The first gradient from the top to the middle is a blend of white, to a lightly colored orange.

The second gradient from the bottom to the middle is also a blend of white, but to a slightly darker orange.

The point is there are 2 gradients been used, with 4 colors, 2 whites and 2 orange variations.

I would like to do this on a Canvas but don't know how to. The colors could be anything at all, above was just an example.

How may I do this?
