Baby skin color calculator
Choose the parents’ skin tones and optionally add grandparents. Explore a visual simulation for fun; its percentages are not validated genetic probabilities.

Choose at least one skin tone to explore the simulation. No result is shown while all tones are unknown.
How does this skin tone simulation work?
The six swatches are assigned positions from 0 to 5. The tool averages the positions of the family members you have entered, then draws a bell-shaped distribution around that average. Its width is fixed in the code, not measured from genetic data. The displayed percentages add up to 100% within this visual model only.
What does “Unknown” mean?
“Unknown” leaves that person out of the average. It does not assign a medium skin tone. If every entry is unknown, there is no calculation or result.
What do grandparents change in the simulation?
Every person entered has equal weight, whether a parent or a grandparent. Adding a grandparent can move the average. This is a design rule of the simulation; it does not reconstruct genes or measure how much a grandparent influences a baby’s skin tone.
Can family skin tones give reliable genetic percentages?
Skin pigmentation is influenced by many genes. A visual choice among six swatches does not identify those variants. This simulation has not been validated to estimate an individual baby’s skin tone probabilities.
Are these swatches a scientific skin color scale?
They are illustration guides, not a standardized pigmentation measurement or ancestry categories. Choose the nearest swatch or leave “Unknown”. Lighting and screens can change how a shade looks; the baby illustrations do not show an exact color at birth.
