Hand tools are chosen by fit, not by handle colour. A socket that grips a rusted hex, a ratchet with enough teeth to swing in a tight wheel well, and a torque wrench that turns a guess into a figure: that is most of the list.
Two specifications decide most socket purchases: drive size and socket profile. A 3/8-inch set covers the majority of fasteners on a car, while 1/2-inch is for wheel nuts and suspension. Six-point sockets put metal on the flats and hold a damaged hex longer; twelve-point sockets are quicker to seat but round a soft nut sooner.
Then there is the material. Chrome sockets are hard and thin, which is what you want in the hand; impact-rated sockets are softer and thicker so they absorb the shock of a power tool instead of cracking. Mixing the two is how a socket splits.

The everyday set: shallow and deep sockets, extensions and a ratchet that swings in tight spaces.
