amusement has some obvious value, like when watching an active toddler. see him learning colours and numbers with obvious delight. i showed him this torch ginger photograph i made in a tropical place on the edge of a jungle what colour is that? i said, pointing at an orange place. he named orange, then green when i pointed at a leaf. then i touched something and colour changed as he watched. he saw it happen and the colour of excitement is true colour. he may have said, if he had the words.
