Hearts Come In All Colors
Did you know? - The day is most closely associated with the mutual exchange of love notes in the form of "valentines". Modern Valentine symbols include the heart-shaped outline, doves, and the figure of the winged Cupid. Since the 19th century, handwritten notes have largely given way to mass-produced greeting cards.
Did you know? - Purple is a general term used in English for the range of shades of color occurring between red and blue. In additive light combinations it occurs by mixing the primary colors red and blue in varying proportions. In subtractive pigments it can be equal to the primary color magenta or be formed by mixing magenta with the secondary colors red or blue, or by mixing just the latter two, in which case a color of low saturation will result. Low saturation will also be caused by adding a certain quantity of the third primary color (green for light or yellow for pigment). There is a disagreement over exactly which shades can be described as purple, some people preferring more precise terms such as magenta or heliotrope for particular shades. A difference in retinal sensitivity to red and blue light between individuals can cause further disagreement.
In color theory, a "purple" is defined as any non-spectral color between violet and red (excluding violet and red themselves). The spectral colors violet and indigo are not purples according to color theory but they are purples according to common English usage since they are between red and blue.
Did You Know? - The earliest documentation of fireworks dates back to 7th century China where they were first used to frighten away evil spirits with their loud sound (鞭炮/鞭砲 biān pào) and also to pray for happiness and prosperity. Eventually, the art and science of firework making developed into an independent profession. In ancient China, pyrotechnicians (firework-masters) were well-respected for their knowledge and skill in mounting dazzling displays of light and sound.
