This is not true.

The Stability of Synthesis Materials
The stability of synthesis materials is represented by the color of the glowing light displayed onscreen while crafting. Each command executed has an effect on stability.

When the glowing light is white, the materials are extremely stable, and the chances of success of synthesis commands are increased. The light may also turn from yellow, to red, to multiple colors flashing rapidly. Though these states represent progressively lower chances of success when executing commands, they also indicate times at which the quality of the synthesis can most easily be enhanced, therefore increasing the likelihood of creating a high-quality item.
