The area around Antares, the globular cluster M4, and the triple star Rho Ophiuchi is awash with multi-colored nebulosity: red, yellow, and blue.  The nebulosity is faint, so it requires longer exposure times than I am set up to accomplish with my equipment and skill level, but stretching one of my images from Big Bend National Park in 2019 starts to show some of the colors.  We can also easily see the streaks of dark clouds streaming away from the area toward the east (left) in the direction of Ophiuchus.  The original image was cropped and enlarged.  Unannotated image.
