The Blue Heart symbol (💙) is one of the hearts and love characters in the AllSymbols catalog. It is part of the family of Unicode heart characters, which split into two visual styles: thin suit hearts from the playing-card tradition and plump emoji hearts in color. The two styles cannot be mixed for visual consistency — pick a style and use it throughout a piece of writing.
Heart characters carry the same casual associations across most contexts: affection, gratitude, support, fondness. Color emoji hearts add a tonal layer — red is direct, pink and purple lean affectionate, blue and green carry friendship and support undertones in many online communities. Conventions are loose; treat them as soft signals rather than rules.
In Unicode, Blue Heart sits at code point U+1F499. Web pages reference it with the HTML numeric entity 💙; CSS rules reference it as a quoted hex escape (the four-digit code prefixed with a backslash); in JavaScript and most modern source-code contexts you can either paste the literal character or use a Unicode escape with the same hex digits.
Suit hearts (♥ / ♡) inherit the surrounding text color through CSS. Color emoji hearts render with the platform’s emoji font and ignore the surrounding color — you can’t tint them with CSS. Pick the style that matches the context: monochrome prose wants the suit heart; chat and social posts usually want the emoji.
If Blue Heart isn’t quite what you need, the Hearts and Love page lists every related character on the site — including Red Heart and Broken Heart. The related-symbols grid below also surfaces the closest sibling characters.
