The True Colours of Coral Glen

Coral sees the world around her through a rainbow of colours not visible to others - a day full of adventure is Treasure Island Gold but one with a maths test is Stormy Canyon Grey. When her beloved grandma dies, Coral can't find the colour to match how heartbroken she is. She makes a bargain with a ghostly boy - she'll stop an evil spirit from breaking the spell imprisoning him in a graveyard and he'll find a way for her to say goodbye properly to Grandma.
