Use white frosting, icing, batter, or another light-colored base
Add a tiny drop of red food coloring
Mix thoroughly
Add more red coloring a little at a time until the shade becomes pink
Use less red for a pale pink
Use more red for a deeper pink
If the color looks too dark, mix in more white base
For a warmer pink, add a small amount of red with a tiny touch of yellow
For a cooler pink, use red with a tiny touch of blue or purple
Use gel food coloring for stronger color with less liquid
Use liquid food coloring sparingly to avoid thinning the mixture
