What is the equivalent of Max Factor "sand" shade foundation which i was using before that i could purchase in Lancome products?

I find the Max Factor "sand" shade matches my facial tone, when it was personally demonstrated & applied to me before with a store beautician. Now i wanted to switch to RENERGIE LIFT MAKEUP SPF20, but confused as to the right tone that is equivalent with max factor "sand". Based on the computer i find it so confusing which is which that matches "sand". Could lancome beauty advisor please assist . . .
