Blood red is a warm color that can be bright or dark red. The bright red color of crimson is often considered the color of fresh blood, but blood-red color may also describe a dark maroon shade of red.
When planning a design project destined for commercial printing, use CMYK formulations for blood red in your page layout software or select a Pantone spot color. For display on a computer monitor, use RGB values.
Use hex designations when working with HTML, CSS, and SVG. Blood red shades are best achieved with the following:
\tHex\tRGB\tCMYK\t
Blood Red\t#bb0a1e\t166,16,30\t0,95,84,27\t
Crimson\t#dc143c\t220,20,60\t0,91,73,14\t
Dark Red\t#8b0000\t139,0,0\t0,100,100,45\t
When working with printed pieces, sometimes a solid color red ink, rather than a CMYK red, is a more economical choice. The Pantone Matching System is the most widely recognized spot color system, and it is supported by industry-leading design software and most U.S. commercial printing companies.
Here are the Pantone colors suggested as best matches to blood red:
\tPantone Solid Coated\t
Blood Red\t7621 C\t
Crimson\t199 C\t
Dark Red\t7623 C\t
