    Looking for the perfect deep green paint color for your home? Let’s talk about Sherwin Williams Thunderous and if it might be right for your home!

    Deep greens are having a moment, and honestly, I hope they never go out of style.

    They’re bold yet cozy, sophisticated yet inviting. They bring an earthy, organic feel to a space while still feeling refined and modern.

    One of my favorite deep greens? Thunderous by Sherwin Williams.

    This stunning shade has a strong gray undertone, making it a total chameleon. It shifts beautifully depending on the light, sometimes looking more green, other times more gray, and occasionally even showing a hint of taupe.

    Today, let’s break down everything you need to know about this rich, moody hue!

    Sherwin Williams Thunderous Paint Color Guide

    Thunderous, Sherwin Williams, SW 6201

    Thunderous is a deep green-gray that feels grounding, organic, and full of depth.

    It balances warm and cool, which means it plays well with all kinds of earth-toned neutrals.

    Sherwin Williams featured Thunderous in its 2025 Colormix Forecast, highlighting it as one of 48 trending hues.

    Undertones

    Thunderous has a cool gray undertone, which gives it an earthy, natural vibe.

    But there’s also a hint of warmth from its subtle yellow undertone, which keeps it from feeling too cold.

    How it looks in your space depends on the lighting:

    • In north-facing rooms with less light, Thunderous looks cooler and darker, reading more like a deep green-gray.
    • In south-facing rooms with lots of natural light, Thunderous appears a bit warmer. You might even see hints of brown or taupe.

    It's very important to swatch colors on your wall to make sure they look good – day and night – in your actual space before committing.
