Meet the Regeneration Trends Mischief Mattes Palette from Revolution Pro. It costs only £8 for this collection of bright mattes.
As you can see from above it swatches very well. In practice, I had a little more trouble with the greens showing up as you can tell from the video.
Overall, as I have played with it more since making the video I do like this palette for the price. Worth getting it for festivals and bright colourful look.
