Change the ratio
Very little of a mix is ever half and half. Shifting the balance moves the result along the range between the two colours.

Why it works
Adding white to grey makes a tint. The hue does not change - only its lightness does, which is why you get light grey rather than a different colour altogether. Keep adding white and it keeps moving towards plain white.
Frequently asked questions
What color do grey and white make?
Grey and White make light grey, #bfbfbf. Mixed in equal parts that is the result you get with paint, ink or any other pigment.
How do I make the result lighter or darker?
Add white for a tint - here that gives light grey. Add black for a shade, which gives grey. Add white a little at a time, because it takes far less than people expect to shift a mix.
What happens if I use more grey than white?
Three parts grey to one part white gives grey. Reversing it to one part grey and three parts white gives light grey instead.
Does this work the same way on a screen?
No. Screens mix light additively, so red and green light make yellow there. These results are subtractive - paint, ink, dye and pigment - which is what people mean when they ask what two colours make.
