General Trend:
While Eridanus has a diverse population of stars, there is a tendency for it to have more cooler, redder stars than some other constellations. This is likely due to its relatively low-density region of the Milky Way galaxy.
Observing:
If you are interested in observing the colors of Eridanus's stars, binoculars or a telescope can help you discern the color differences more easily.
