Answer:
Two elements whose names are derived from the color of blue are indium (atomic number 49) and cesium (55). Indium was named after indigo based on the blue color of its emission spectrum, and cesium was named after the Latin caesius, which means sky blue, because it also showed blue emission spectrum.
