Colour of any object is due to the colour of light reflected by the object. If any object appears green that means that it absorbs all the six colours of light while reflects the green one and thus appears green in colour.
Any object which appears black in colour absorbes all the colours and does not reflect any colour. The object which appears white in colour reflects all the seven colours of light and does not absorb any colour of light.
Heat of any colour is due to the radiations absorbed by the object. As a black object absorbes all the colours of light whille white one reflects all the colours of light thus, black object or black house willbe hot white the white one would be cool.
