I asked my 6 yr old if letters had colours, she told me of course and started rattling some off. She had colours for every letter I asked about too. Many were repeated though, quite a few were red for example. I checked starfall and "her" colours were a 100% match for the starfall list. I asked where the colours came from and she said from her toes up to her head (showing me physically). So then I asked if the colours came from inside her or from starfall. She said inside her. She learned the alphabet on starfall when she was 2-2.5, and clearly completely internalized the colours such that they are "hers", to her now at 5.5...

Makes me wonder how many with synasthesia learn the colour of the letters on their alphabet blocks gor similar)? The colours of the days of the week on the chart in their preschool?
