What color is #3A4F41?
#3A4F41 is named Feldgrau with a perceptual Delta-E distance of 7.33. Its RGB values are (58, 79, 65) and HSL values are (140°, 15%, 27%). The closest Pantone match is Pantone Black C.
How do I convert Hex to normalized 0.0–1.0 RGB floats for Unity or Unreal Engine?
To convert 0–255 integer RGB channels into normalized 0.0–1.0 floating point numbers for game engines (Unity C#, Unreal Engine C++) or shaders (GLSL/HLSL), divide each red, green, and blue channel value by 255. For example, #3A4F41 (RGB 58, 79, 65) yields vec3(0.227, 0.310, 0.255).
What is Delta-E (ΔE) perceptual color distance?
Delta-E (ΔE) is a mathematical color difference formula that calculates Euclidean distance in 3D CIE-Lab color space. Unlike raw RGB subtraction, Delta-E aligns with human visual perception, enabling accurate named color matching beyond basic 148 CSS keywords.
How do I convert digital RGB colors to CMYK for physical printing?
RGB is an additive color model used by screens, whereas CMYK is a subtractive model used by printing presses. Our converter calculates Cyan, Magenta, Yellow, and Key/Black ink percentages from normalized RGB values so your printed brand materials match digital designs.
