Different fabrics need to use different kind of dyeing stuff, like silk and wool use acid one while cotton need reactive one. The weight also affects the extend of absorbing color, even same quality needs to have same color, the outcome will not be exactly the same. Sometimes, designer may want to have 2 or more trim fabrics used together on one style, there may be problem on color matching or fastness.

We, being a manufacturer, we will try to have the potential problem inform customer in advance so that customer can alert and may change the design to avoid the problem.
