Shamrock

Technical Profile

What color is Shamrock? It's a medium cool green with the hex code #5CA111. Shamrock is a distinctive shade in the Behr lineup, and while close cross-brand equivalents exist, its specific blend of cool tone and medium depth gives it a character worth comparing in person. Shamrock has a cool (green) undertone, which affects how it pairs with trim, flooring, and adjacent wall colors. Understanding a color's undertone is key to avoiding combinations that clash — it often matters more than the surface color itself. Shamrock (#5CA111) by Behr is a medium green paint color with a striking intensity that commands attention. It delivers a versatile mid-tone depth that anchors a room without overwhelming it. On the temperature spectrum this shade carries a cool cast, lending calm and collected elegance. In its RGB breakdown, green is the dominant channel, which gives it a subtle earthy, organic quality even under different lighting conditions. A Light Reflectance Value of 53 gives it moderate light reflection, striking a balance between brightness and depth. This mid-tone green adds grounding, nature-inspired energy to home offices, living rooms, and open-plan kitchens. A satin or eggshell finish brings out the richness at this depth, and the slight sheen makes walls easier to maintain. For color coordination, Shamrock pairs beautifully with purple tones for bold complementary contrast, or with neighboring green and yellow hues for a harmonious, flowing palette. Its cool (green) undertone means trim and ceiling whites should lean neutral to avoid a jarring clash. If Behr is unavailable in your area, close cross-brand alternatives exist from Valspar, Benjamin Moore, Hirshfield's and others. In terms of mood and atmosphere, Shamrock delivers a composed, professional calm often favored in contemporary and Scandinavian-inspired interiors. Designers often reach for shades like this when the goal is to shape how a room feels, not just how it looks. This shade is a natural fit for organic modern, biophilic, and mid-century aesthetics. As part of the Behr palette, Shamrock benefits from a curated selection of coordinating colors that the brand recommends for trim, accent, and ceiling pairings. As with any paint color, Shamrock can shift noticeably between natural daylight, warm incandescent, and cool LED lighting — testing a sample swatch on your wall under different conditions is always recommended. Mid-tone shades like this look best when balanced with a mix of textures — think leather seating, brushed brass hardware, woven wool, and raw-edge wood. You can order Shamrock (S-H-420) directly from Behr or through major paint retailers, and we recommend purchasing a peel-and-stick sample to preview it on your wall before buying gallons.
