Well I have been hard at work ( cough, cough.... playing with sparklecrack really isn't hard work! ) duping a colour from my Coastalscents 88 metallic palette, seen here. The one I was attempting to dupe was the last colour in row 9, it's a metallic red plum colour.
I swatched the original colour on my arm and started scrounging through my bottles of pure pigments looking for something similar to work with and ended up with a stack of colours to start with and some extras to use to tweak it out to get the shade close.
Using exact measurements and writing everything down as I went, I ended up with this set of variations :D
The colour I was attempting to dupe is circled, and the others are the many variations of dupes I made, I finally settled on one I thought was close, but when swatched side by side, my dupe had more of a purple/blue tone than the original had..... mine is on the left and the original is on the right.
So back to the drawing board, starting with a different base toned red. This resulted in many more attempts :) One of which I was very happy with, again the circled colour is the one I was duping.
I think I got close, what do you think?
Then I felt like just having a random play to create a deep brown with blue undertones, here is some of the many attempts at that, I did come up with one I am happy with :D
Does anyone have any high end colour they wish they could find cheaper dupes for, or have dupes for hard to get colours and brands?
