# Regional Prompt with Reference Image You may want to have more control while using a regional prompt. Here, we bring you a demonstration of using a reference image to draw a color map and using the reference image in the control layer. **How does it work?** In this example, we want to generate an image of a woman with half white hair and half black hair. First, open the color map drawing canvas. Click the "Background" button to select a reference image.

Now, let's draw a color map on the reference image. We want the woman to have half white hair on the left and half black hair on the right. We'll use the color red for the left part of her hair and yellow for the right part.

Here is a final color map we have. Next step is to write prompts for each area.

Don't forget to add a control layer with the reference image. We used a depth control here.

Okay, now we can click a button to generate images! Below are the resulting images of this configuration in both the realistic model and anime model.
