I would all 3 approach to allow her to be creative even when learning new things

Colouring book... and then telling my kid my choices of colour for the picture

All of the above! Everyday situations are learning opportunities to children.

we use different toys para nakakapaglaro kame habang nagtututo sya ng colors.

Visual and experiential learning always trumps route memorization

Painting is a good option, I usually point out the colors

Do colouring while asking them to name the colours

And mixing colours to make other colours...its fun

We do all of the above the reach my child colours

I use a mix of all to start sharing to my son
