Explanation:

the colour of transition elements is due to the presence of unpaired electrons. cu+ is colourless as its outermost configuration is 3d10 ...so there are no unpaired electrons which causes the colour . In the configuration of cu+ atomic number is 28 after removing one electron that means all the the orbital of cu+ are fullfilled. Due to this there is no any free electron to go in higher energy level and provide the color. That's why cu+ is colourless and cu++ is coloured.
