Google has unveiled a new range of skin tones to develop its artificial intelligence systems.
The new system is called the Monk Skin Tone Scale. It is named after Harvard University professor Dr Ellis Monk and has 10 skin tones.
Google says it will replace outdated skin tone scales which have a bias toward paler skins.
Machine learning is used by a lot of technology including cameras that recognise a face to unlock a phone.
But researchers need to train the technology so that it can recognise a wide range of people. This new system will make the technology more accurate.
The last system was called the Fitzpatrick scale. This was made in 1975 and it divided skin into six tones.
Google says eventually the new scale will be used across all its products.
