Background: Coated aesthetic archwires are currently the existing solutions for the esthetic problem, but the color ofthese archwires tends to change overtime. This study was aimed to evaluate the color stability of different types ofesthetic archwires from four different companies at different time periods after immersion of two different stainingdrinks which are tea and Pepsi cola.Materials and methods: 48 specimens were prepared, each specimen contains 10 aesthetic archwires; and weredivided according to type of solution into two groups: A (tea) &B (Pepsi cola); each group contained 24 specimens(12 specimens were immersed in the staining solution as 4 specimens for each time intervals and 12 specimens wereimmersed in distilled water as control group). Each subgroup contains one specimen from each company. Colormeasurements were performed by means of a computed spectrophotometer according to the CommissionInternationale de I’Eclairage L*a*b* system, and color changes (ΔE*) and National Bureau of Standards units.Results: Both staining solution caused color change in variable degree and the higher amount of color instability wasfound for the archwires from the Hubit Company while the least amount of color change was for the archwires fromthe Orthotechnology Company.Conclusion: The tea caused highly significant change on the aesthetic archwires which is higher than the effect ofthe Pepsi cola
