Thank you for your question.
We follow the position that stains on disposable pantyliners of any color, including white, do not render a woman niddah or interrupt her seven clean days. You can learn more about halachic considerations with feminine hygiene products here, and about the laws of stains here.
For women who follow halachic rulings that prefer black disposable pantyliners, we recommend searching online. Manufacturers are constantly producing new varieties of pantiliners, and discontinuing old ones.
Stains on reusable cloth pantyliners are evaluated like stains on underwear. Reusable cloth pantyliners in various colors can be found online, and are fine for avoiding problems with stains as long as you choose patterns that don’t include white or off-white.
B’hatzlacha!
