Yeah.. having real trouble finding a combination to get it. Have been trying for 2 hours now, so if anyone could help, thanks.

Value of each color:

 

 

 

 

The image below shows what the value of each color is. To figure out the shape to put into the machine, you need to multiply the number of sides on the shape by the amount of blocks associated with that color. The colors from left to right are red, orange, yellow, green, blue, indigo and violet. You can speak to Brimstail to get more shapes.

 

 

 

On the following image for the top number, you need one shape that makes up the number six. There are two possible solutions for this number. You could have an indigo circle or you could have an orange triangle. For the middle number, you need two shapes to make up the number five. You could use a green circle and a red circle because green has the value of 4 and red has a value of 1, and each circle has 1 side so you get 4+1 = 5.
