We started with drawing with white pencil on black paper (I taped it to the table to stop it from moving around).
We also painted with white poster paint on black paper.
Explored different kitchen tools as painting instruments (also white!)
And used a sponge brush.
Then the other day we made a collage on (you guessed it!) black paper using white school glue, cotton balls and scrap paper. I put glue in a bottle cap and gave her cotton swabs for glue application. This is our setup.
Kitten really preferred to use her fingers to apply glue. She thought it was paint and refused to stick anything to it, despite me showing her. May be next time.
We also did a "white hunt" around the house. Kitten really did not understand what I wanted from her but she was excited to announce one found object after another white.
We played with white pipe cleaners, twisting them into shapes. Kitten was very amused by this possibility. For about 5 seconds… Oh, well, you don't try, you don't know what they enjoy doing.
I found every opportunity to say "Look, white …" or ask her about white objects what color they are. We also ate some white food but I never took a picture of it. Here are some white foods that you may want to arrange in a "white meal" - cauliflower, chicken, rice, white bread, sour cream, milk, marshmallows, sugar (I arranged a white bread - sour cream - sugar sandwich for Kitten, she LOVED it).
Now moving on to black color.
