Can You Wash Lights and Darks Together on Cold?: A Quick Guide to Sorting Laundry Like a Pro

Sorting laundry is a time-honored routine: keep your lights and darks separate. But is it really necessary, especially if you wash everything in cold water? The answer depends on a few factors, but in general, washing lights and darks together on cold is less risky than using warmer temperatures. That’s because cold water reduces the chance of dyes bleeding from dark fabrics onto lighter ones. However, brand-new dark garments or highly saturated fabrics still pose a transfer risk, even in cold water. If you want your whites to stay crisp and your colors to remain bold, it’s best to sort when possible—especially for items you prize most. As a designer, I always recommend reading garment care labels not just for longevity, but to help maintain the intended palette and texture of your space. After all, the way your linens and fabrics wear over time impacts the aesthetic harmony of any interior, and paying attention to these details keeps your home visually cohesive. For homeowners inspired to restyle their spaces, leveraging a smart room planner can help you select new textiles, patterns, and layouts without commitment.

Tips 1:

Test new garments for colorfastness before mixing. Dab a damp white cloth onto the fabric—if color transfers, continue to wash it separately for a few cycles. Turning dark and colored items inside out can also help preserve dyes.

FAQ

Q: Will cold water always prevent colors from bleeding?

A: While cold water reduces the risk, it doesn’t eliminate it, especially for brand-new, highly pigmented clothing.

Q: Is it okay to mix lights and darks if I use a color catcher sheet?

A: Color catcher sheets can help, but they’re not foolproof. Sorting is still safest for prized items.

Q: What if I only have a small load of laundry?

A: If you must mix, use cold water and avoid washing new darks with delicate lights. Prioritize colorfast, older garments.

Q: Does sorting laundry really impact my home’s interior look?

A: Over time, muddling colors can dull textiles, which affects the freshness and harmony of your space’s design.

Q: How else can I protect my fabrics during washing?

A: Besides sorting, use gentle cycles, appropriate detergents, and avoid overloading your washer to reduce wear and tear on your linens and clothes.
