You pulled the red cord to open the door during a power cut and it barely moved. Lifting it took your whole weight, and when you let go it came down hard.
Choosing the right spring is a matter of weight, not colour. Extension springs are rated for the weight they are meant to lift, and the correct pair for your door is found by weighing the door itself with the opener released, then checking that figure against the wire size, coil diameter and length of the old springs. Paint colour on the end coil is only a hint; older springs fade, get overpainted or were never quite right to begin with. A pair matched to the measured weight gives a door that holds at half height and lifts with one hand, and an opener that works lightly.

Scene 1
The question the industry's own inspection checklist asks of every extension-spring door is whether each spring has a cable running through its centre, anchored at both ends. The technician checks for it on both sides, then checks its condition: a cable that is frayed, kinked, anchored to a loose screw or simply tied off to the hanger is not doing its job. Doors installed decades ago often have none at all, and doors that had a spring changed by a previous owner sometimes have one side fitted and one forgotten. Fresh containment cables go on with the new springs, and their anchor points are set into solid framing so that a spring which breaks stays on its cable.
Scene 2
Before a spring is hung, a containment cable is fed through the centre of its coil. One end is anchored at the rear, to the hanger or the framing behind it, and the other is run forward past the pulley and fixed to the bracket at the front of the track or to the wall, with enough slack that the cable never carries load while the spring works. The cable is checked to be clear of the pulley wheel and the lift cable so nothing rubs. Both sides are done the same way, whether or not the old installation had them. A spring that breaks in future is held on the cable rather than crossing the garage.
Scene 3
Twice a year, in spring and before winter, a can of garage-door lubricant does most of the maintenance the springs need. Spray a light coat along each extension spring, working from the hanger to the pulley; it slows rust in a damp garage and quiets the coils. Put a drop on each pulley axle and on the bolts through the pulley forks, then on the hinge pins and roller stems. Leave the tracks dry and wipe them clean, since grease there collects grit and stops rollers rolling. Heavy grease and general-purpose oil are avoided on the springs because they hold moisture against the wire. Run the door a few times afterwards to spread the film.

Springs are rated in cycles, one cycle being a full open and close, and a standard set is built for a number in the ten-thousand range. A door used four times a day gets through that in several years; a door used a few times a week takes far longer. An unheated, damp garage shortens the figure through rust. Regular lubrication and a door kept in balance stretch it out.
It is put right as part of the job. The rear hanger takes the full pull of the spring on every cycle, and lag screws driven into thin plywood, a split joist or drywall work loose over the years, which is often why a door slowly goes out of balance. The technician re-fixes the hanger with fresh lag screws into solid framing, or adds a length of angle iron to reach it, before the new springs are hung.
Because the door is now much lighter for the opener to move. Over the years, as the old springs weakened, the opener's force setting may have been turned up to keep the door going, and its travel limits were set against a door that sat differently on the floor. Left alone, that extra force would push the newly balanced door too hard. Resetting force and travel, then repeating the reversal tests, matches the opener to the door it now has.
