Foundation Shade Mixing
Mix two foundation shades and see each one's share.
About Foundation Shade Mixing
Blending two foundations produces an intermediate tone, and each shade's share is its volume as a fraction of the total. Custom-blending a shade that matches better than either bottle alone is a common trick for seasonal skin tone changes.
Formula
Foundation Shade Mixing
Shade A share = A volume / (A + B) x 100

- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
