Revlon ColorSilk Hair Color: 12 Natural Blue BlackRevlon ColorSilk 12 Natural Blue Black is a striking, high-shine shade designed for those who want a deep black finish with a visible, cool blue undertone. This shade is especially popular for its ability to look "inky" and multidimensional, catching the light with a subtle sapphire glint. Like all ColorSilk products, it is ammonia-free and features Revlon’s 3D Color Gel Technology™ to ensure the color looks natural and vibrant rather than flat or solid.
Key Features & Benefits
Dramatic Blue-Black Finish: Delivers a rich black base with a cool blue tinge that adds depth and a "mirror-like" shine to the hair.
Ammonia-Free Formula: Provides a gentle coloring experience with no harsh chemical odor, making it safer for the hair and scalp.
Bond Repair & Nourishment: The 2026 formula is often enriched with a Bond Repair Complex and Vegan Keratin Fillers, helping to strengthen hair and reduce breakage by up to 98%.
Silk Protein & Keratin: Infused with Silk Amino Acids that penetrate the hair shaft, leaving your hair feeling softer and silkier than before you colored.
100% Gray Coverage: Even the most stubborn grays are fully saturated with deep, long-lasting pigment.
UV Defense: Built-in protection helps prevent the blue tones from fading into a dull brown when exposed to sunlight.
Shade Comparison: 10 vs. 12
10 Black Noir: A pure, classic jet-black. It is neutral and deep without any specific secondary tones.
12 Natural Blue Black: Similar in darkness to 10, but with added cool blue pigments. It appears "cooler" and more reflective under bright light or sunlight.
Application Guide
Preparation: Use a barrier cream (like petroleum jelly) around your hairline, as blue-black pigments can be quite staining on the skin.
Mixing: Pour the colorant into the developer bottle and shake well.
Timing: Process for 25 minutes. If you are covering significant gray hair, you may leave it for up to 35 minutes.
