Electronic devices including colored glass-based components

An electronic device comprising:

• an enclosure comprising:
• an enclosure component defining a side surface of the electronic device;
• a front cover assembly coupled to the enclosure component, defining a front surface of the electronic device, and comprising a front cover member;
• and
• a rear cover assembly coupled to the enclosure component, defining a rear surface of the electronic device, and comprising:
• a rear cover member formed from a colored glass material and having a dielectric constant from 5 to 6.5 in a frequency band from 5 GHz to 40 GHz, at least a portion of the rear cover member having:
• an average transmission for visible light greater than 75%;
• and
• a chroma value of at least 1.75;
• and
• an optical coating disposed along an interior surface of the rear cover member;
• a display positioned below the front cover assembly;
• and
• a transceiver component of a wireless communication system positioned below the rear cover assembly.

An electronic device comprising:

• a display;
• a rear-facing camera array comprising an array of camera modules;
• and
• an enclosure comprising:
• an enclosure component defining a side surface of the electronic device;
• a first cover assembly defining a front surface of the electronic device, the first cover assembly comprising a first cover member positioned over the display;
• and
• a second cover assembly defining a rear surface of the electronic device and comprising:
• a second cover member formed of a colored glass, a first portion of the second cover member having a first L* value and a second portion of the second cover member having a second L* value, less than the first L* value and defining an array of through-holes, each camera module of the array of camera modules extending into a respective through-hole of the array of through-holes;
• and
• a coating disposed along an interior surface of the second cover member.
