Is it possible to create a multiple-coloured noise stim?

Hello,

I have created a uniform noise stim on builder but I want to make a CFS style noise. In noise stim settings, there is only one choosing option to define noise colour, but i want to use multi-colours. Are there any code to define more than one colour?

Here is my uniform noise stim, I want to change these pixels colour but as I mentioned there is just one option to define colour (in my example, its red). Is it possible to change these pixels colour, rapidly?
