Hi. I think a more appropriate value range for this paint should be 1.66-2 ref. The paint seems to be very popular and is selling easily for 2 ref. I haven't found many trades selling it below 1.66 ref. The cutoff for potential buyers seems to be 2 ref. Proof:

1.22 ref

So as you can see the paint sells easily at the 1.66-2 ref range. Most people seem to be selling in this range too. I myself have sold 7 in the past week at the price of 2 ref. Therefore I suggest we change the value of Aged Mustache Grey to 1.66-2 ref.
