String Tips #4 - Does the color of a string change its properties?
One might think that the color of a tennis string is merely a matter of aesthetics. In reality, it reveals something deeper: the chemical composition of the material, and therefore the string's behavior on the court.
Why color affects rigidity
The color is directly related to the pigments and additives used during manufacturing. Generally speaking, dark strings are slightly stiffer than light strings. For example, Razor Soft Lime and Razor Soft White are more flexible than Razor Soft Carbon .
➤ Tecnifibre 's tip : Opt for light-colored strings. In addition to being more flexible and comfortable, they absorb less heat from the sun, allowing them to better maintain their tension over time.
Flexibility vs. rigidity: what impact on your game?
A softer string offers more comfort, feel, and power. Conversely, a stiffer string promotes control: it responds more directly and predictably.
The effect of heat on voltage
Darker colors absorb more solar heat. On an outdoor court in sunny weather, dark strings heat up faster. Therefore, increased temperature means accelerated tension loss. Opt for a lighter color to maintain your performance for longer.

Key points to remember:
➤ Darker strings = stiffer feel → more control.
➤ Lighter strings = softer feel → more comfort, touch, and power.
➤ Darker colors absorb more heat and lose tension more quickly.
"Dark colors attract heat and lose their tension faster. Go for lighter colors."
