  • The original Rudolph did not have a red nose. In that day and age, red noses were seen as an indicator of chronic alcoholism and Montgomery Ward didn’t want him to look like a drunkard. To complete the original picture, he was almost named Reginald or Rollo.
  • The Christmas wreath was originally hung as a symbol of Jesus. The holly represents his crown of thorns and the red berries the blood he shed.
  • The three traditional colors of most Christmas decorations are red, green and gold. Red symbolizes the blood of Christ, green symbolized life and rebirth, and gold represents light, royalty and wealth.
  • Tinsel was invented in 1610 in Germany and was once made of real silver.
  • The oldest artificial Christmas trees date back to the late 1800s and were made of green raffia (think grass hula skirts) or dyed goose feathers. Next the Addis Brush Company used their machinery that wove toilet brushes to create pine-like branches for artificial Christmas trees that were less flammable and could hold heavier decorations.
  • ‘Jingle Bells’ – the popular Christmas song was composed by James Pierpont in Massachusetts, America. It was, however, written for thanksgiving and not Christmas.
  • Coca-Cola was the first company that used Santa Claus during the winter season for promotion.
  • Hallmark introduced their first Christmas cards in 1915.
  • The first recorded date of Christmas being celebrated on December 25th was in 336, during the time of the Roman Emperor Constantine. A few years later, Pope Julius I officially declared that the birth of Jesus would be celebrated on that day.
  • Santa Claus's sleigh is led by eight reindeer: Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Dunder (variously spelled Donder and Donner), and Blixem (variously spelled Blixen and Blitzen), with Rudolph being a 20th-century inclusion.
  • Outdoor Christmas lights on homes evolved from decorating the traditional Christmas tree and house with candles during the Christmas season. Lighting the tree with small candles dates back to the 17th century and originated in Germany before spreading to Eastern Europe.
  • That big, jolly man in the red suit with a white beard didn’t always look that way. Prior to 1931, Santa was depicted as everything from a tall gaunt man to a spooky-looking elf. He has donned a bishop's robe and a Norse huntsman's animal skin. When Civil War cartoonist Thomas Nast drew Santa Claus for Harper's Weekly in 1862, Santa was a small elflike figure who supported the Union. Nast continued to draw Santa for 30 years, changing the color of his coat from tan to the red he’s known for today.
  • Christmas 2018 countdown has already begun. Will you be ready???
  • Why do we love Christmas? It's all about the traditions. In this chaotic world we can miss the "good old days." Christmas reminds us of that time.

anyone tried mixing R B Y lights to make different colors?

Recommended Posts

has anyone tried laying the 3 primary colors on top of each other and mixing them to make other colors? Seems like it should be possible...like the big LED TV screens. Anyone tried this?

*grin* Actually it's Red, Green and Blue that one uses to do this. There are tons of "RGB" LED units already on the market. Go to somewhere like PSSL.com and check out the DMX, RGB LED wash units for example. Also, the FireFly pixel strings from D-Light do this exact thing as well, only you get 16 pixels per string that you can control individually.

Yep, I have a string of RGB c6 leds all zip tied together in my basement and tried to do this. Don't bother. If you are viewing it from 3 blocks away they might blend but 30 or 40' away and they are just RGB due to size.

I would think if you were doing arches with a sleeve you could accomplish this... I just ordered my sleeves and should have some arches done in a month... I will try this out.

Are you talking about 3 separate strings one red and one green and one blue? I never thought about trying that and I bet it would work well with some type of diffuser/sleeve.

I look forward to seeing how it turns out!

They need to be VERY close together for this to work and you cannot get them close enough to make it happen. I have seen surface mount LEDs that use this trick and the distance between the different colors is about 1mm. A diffuser may work but I doubt it.

If its a continuous string of them then they can be quite large and far apart - I did a test with 5mm LEDs spaced end to end and even right by it they were fine.

Saw a thing someone did on instructables I think it was where they used pingpong balls to act as a diffuser for some RGB leds, so separate ones would probably be ok in it.
