# Regional Prompt (color mask)

<mark style="background-color:orange;">**What is regional prompt?**</mark>

It is a tool that allows you to specify different prompts for different regions.

<mark style="background-color:orange;">**Why use a regional prompt?**</mark>

Have you ever found it difficult to create multiple subjects in a single image? Here is an example:

<figure><img src="/files/nJZWfxu1tXlP1ka8Buek" alt="" width="375"><figcaption><p>try to generate a image with 2 girls. one girl with school uniform on the left. another one with bikini on the left</p></figcaption></figure>

You will probably get the result below with the above prompt. The resulting image is definitely not what we are thinking of.

<figure><img src="/files/O4BiPI0PipAt25HAiAoT" alt="" width="375"><figcaption></figcaption></figure>

Regional prompt is your helper. We can specify different prompts for the girl on the left and the girl on the right using the regional prompt.

<mark style="background-color:orange;">**How does it work?**</mark>

Enable the regional prompt feature with the toggle. It will take you to a color map page.

Draw a color map for image composition. For example, we want a girl with a school uniform on the left in the <mark style="color:red;">red</mark> area, a girl with a bikini on the right in the <mark style="color:yellow;">yellow</mark> area, and a starry sky on top in the white area. Here is the color map we drew:

<figure><img src="/files/cmx08Ieo5GqS2TpSS53Q" alt="" width="375"><figcaption></figcaption></figure>

Great! We have a color map now. Let's create a prompt for each area. We enter the prompt for each area as shown below. \**Remember to specify "2 girls" in the prompt; otherwise, it will become "1 girl" wearing half a school uniform and half a bikini.*

<figure><img src="/files/qQWlLehlZ0cBeeHBO6Hp" alt="" width="375"><figcaption></figcaption></figure>

Start generating! We have a great image with the correct composition!
