Both being metals they are not entirely different. Both conduct electricity and heat well. Although they are of different colours they both have metallic lustres. However, potassium is far more reactive than copper and its chemistry is correspondingly different. For more details see the pages on wikipedia.
The compound CuSO4·6H2O, known as copper(II) sulfate pentahydrate, appears as blue crystals.
Flame colours depend on just the metal ion. All copper compounds give the same colour, green.
Copper compounds are used in fireworks to produce blue and green colors in the flame. When heated, copper ions emit these vibrant colors, adding variety to the visual display of the fireworks. Copper compounds like cupric chloride and copper oxide are commonly used in pyrotechnics for this purpose.

Different colours appear because it is the way the human eye perceives them. Colours have different wave lengths and human's eyes can see that which makes you see it as a colour. The thing that makes colours different is the size of the wavelength.
