Understand what the chart was written for
DASMA’s spring color document is intended for manufacturers, not as a homeowner replacement guide. It distinguishes torsion and extension spring systems and says color does not capture every design characteristic. A color remembered from an older installation is therefore not a reliable ordering specification.
Preserve information without disturbing the system
If a label or mark is visible from a safe standing position, mention it with the door manufacturer and previous service paperwork. Do not unwind, stretch, detach or handle a spring to obtain more information. A missing or painted-over mark is a reason for proper identification, not a reason to guess from an online photograph.
Ask for the result of the selection process
A repair proposal should identify the applicable door and the replacement scope. Ask how the selected parts match the existing assembly and whether related wear changes the work. This discussion is more useful than choosing a supposedly stronger spring by color or price.
Your questions
Can two springs with the same color be different?
Yes. Color coding does not capture the complete spring design, and codes are not a substitute for the manufacturer’s full identification requirements.
Should I order a replacement from the color alone?
No. Have the door and counterbalance identified by a trained door-systems technician before replacement parts are selected.
