The Sunflower, a banana, the colour of a fried egg and a smiley. What is common in them? The Colour Yellow. PP1 children celebrated yellow day on 20 July 2020. On that day, the children dressed in yellow and learnt about the common things in yellow. They also learnt the scientific fact that yellow is the first visible colour in the spectrum and that is the reason why sign boards and school buses are painted yellow in colour. The teachers made the children colour popsicles in yellow and fish with yellow scales to finally call it a day or rather a yellow day.
