Color depth refers to the number of unique colors that a sensor can faithfully capture. Cameras with better color depth will demonstrate smoother transitions from one color to the next, and avoid "banding" in areas with subtle shading. (Blue skies are an example of where you might see color banding.)
More color depth is generally better, but you'll struggle to notice a difference between two cameras with less than 1 bit of difference. Color depth above 22 bits is considered excellent.

Cameras with higher effective ISO will be better choices for indoor photography, night shooting, and indoor sports photography, especially if you intend to make large prints.

A6500 test data on DxO Mark ZS40 test data on DxO MarkCameras with more dynamic range allow you to take photos with dramatic differences in highlight and shadow areas while retaining detail in both.
Think of a brilliant sunset on a rocky beach: Bright sunset in the background, with dark rocks in the foreground. High dynamic range means more of the extremes will be faithfully reproduced.

A6500 test data on DxO Mark ZS40 test data on DxO MarkComfortable, premium body with good controls; Touch-screen for subject selection; Hybrid image stabilization system; Excellent image quality; Better high ISO JPEGs than the A6300; Extremely fast 11.1 fps burst capture; Very deep buffers for raw and JPEG alike; 4K video capture with no pixel binning
Pricey for an APS-C camera; JPEG colors aren't the most accurate; Very slow buffer clearing; Laggy touch-pad AF function; Poorly-placed movie button; No headphone jack; Mediocre battery life
