/* Preparation: recognition of the background colour by the sprite */
We explain that at the beginning we will learn to recognise if the sprite has entered a square of a certain colour, i.e. is it touching a given colour. <br/>
'''Task:''' We ask the students to double click the stage or the stage icon located in the bottom left corner. <br/> ::''We remind them that the appearance of the screen changes, and in the top centre of the screen we can go to the Background tab to change the stage.''<br/>
