If you intend to visualize both the energy and intensity in astronomical images, a 3-color image might be a good solution, especially if intended for the general audience or public/press releases. This page describes how to create 3-color images from both UVOT and XRT data, or from a combination of UVOT and XRT data.
Read this thread if you want to: Create "true" 3-color images in different energy and intensity scales.

3-color images can be created in various ways. Some of the more common methods are described below.
This thread assumes that you have created three FITS files in three different filers (UVOT) or energy bands (XRT).
