No one can give the answer of this particular question as everybody has their own aesthetic sense. There are number of choices available in colour and pattern for the membrane shutter. There is no certain rule about the colour of the modular kitchen shutter but in some cases people use dark colour in the base cabinet shutters and light colour in the top cabinet shutters. Whereas some people like same colour shutter in the complete kitchen. Some people want gloss shutters while some likes matte finish shutters.
