Yes, my interior is Kertrel Tan, a rather hard color to copy, and the Colourlock dye matched perfectly. I had a scratch on the side of the driver's seat that resulted from a watchband rubbing against the leather when engaging and releasing the hand brake which I understand is a common issue due to the location of the brake handle. The fix took me about 5 minutes (I used a Qtip) and the scratch is still invisible. Great product. They have videos for more extensive projects, but mine was quite simple.
