Today, magenta dye is only craftable as follows:
2 magenta dye = 1 purple dye + 1 pink dye

Breaking these components down, we get:
4 magenta dye = 2 red dye + 1 blue dye + 1 white dye

It then follows that the following formula should work:
2 magenta dye = 1 red dye + 1 light blue dye

Is the above crafting addition something that would be acceptable?

Thanks!
