Dr Colorchip has been around since about 2006 and I started using it around 2008. The Tesla kit comes with 0.5 oz paint and 1 oz blending solution. The closet Dr Colorchip kit to this is the Basic Kit which is $44.95. The other Dr. Colorchip kits have more paint and or more blending solution. The limiting factor of the kit is the blending solution.
