Abstract
In one example a method of additive manufacturing includes obtaining object model data and colour data. The object model data describes at least portion of an object to be generated in additive manufacturing using a build material having a first colour and a fusing agent having a second colour different from the first colour. The colour data describes an intended colour of at least portion of the object to be manufactured by additive manufacturing. The intended colour is substantially the first colour, the second colour or a colour therebetween. The method includes determining object generation instructions to apply the fusing agent to a first region of a layer of the build material. The first region of the layer corresponds to portion of the object and the instructions are to apply fusing agent at a contone level such that the colour of the portion of the object corresponding to the first region of the layer of build material is substantially the same as the intended colour as described by the colour data.
