Vincent van Gogh was a big fan of violet and often used it in his paintings, including his renowned starry night series. He supposedly wrote this in a letter: “The night is even more richly colored than the day, colored in the most intense violets, blues, and greens. Some stars are lemony, others have a pink, green, forget-me-not blue glow.” For this week's remembrance, discuss what the color violet means to you. Share a photo of an violet object that means something to you (no identity-revealing details, please!), or make a collage of meaningful violet items using images from the internet. Either way you do it, please include at least two sentences on why you have chosen that particular object or objects.

Violet is also a popular given name. A particularly notorious example is the character of Violet Beauregarde who fell afoul of Willy Wonka’s experiments with 3-course Dinner Gum in Charlie and the Chocolate Factory. Violet actually made it passed the first obstacle, successfully navigating the river of molten chocolate. But imagine you were their and weren’t so lucky. Find your way across the islands of nougat in the chocolate river by solving the following Hashi. There are no more than two bridges in the same direction. Bridges can only be vertical or horizontal and are not allowed to cross islands or other bridges. When completed, all bridges are interconnected enabling passage from any island to another.

The name for indigo actually comes from the ancient dye of the same name, with 'indicum' in Latin meaning 'Indian'. Makes sense since the dye was transported to Europe from India. It was added to the color spectrum of the rainbow by Sir Isaac Newton and can often include shades of blue! It is a very inclusive color.

Blue is one of those colors that seems to carry so many different feelings in it.

To solve the puzzle, fill all squares correctly. Numbers show how many “boat squares” are in each row or column. Ships cannot touch, not even diagonally.

Green is one of the colors that seems to be tied closest to nature. For me, it means my plants and the little veranda garden that I have mostly for my herbs and small vegetables. It is not that difficult to upkeep, most of the work is keeping my cats from getting their paws on cherry tomatoes. For this week's remembrance, discuss what the color green means to you.

Green is everywhere. You can find it in lush forests, rolling hills, minty sweets, sea glass, and even school robes. Each shade of green has its own history, especially those that were man-made. Some were once so rare they were worn only by royalty or made from surprising (and sometimes dangerous!) ingredients. Others became tied to nature, healing, or even magic. Choose one of the shades of green below and write a historical piece on it in at least 100 words. If you choose the same shade as someone else, please make sure to include some different information.

Yellow might not be the first color that comes to mind when you think of movies, but once you start noticing it, you will see how often it is used, and how much of an impact it makes. It stands out in a crowd of nameless extras, bold, bright, and impossible to ignore. On a movie poster, yellow practically shouts at you 'look at me'. Pick an HOL-appropriate (think latter Harry Potter books) movie that heavily features yellow on its poster or during an iconic scene.
