I have the shirt in the color combination Forest Alchemy. This means: a rather dark blue-green with pink underarms. The upper arms are inconspicuously printed with a pattern (bees, flowers, mushrooms,...). I like the design and the colors. If you're not a fan of Forest Alchemy, there are two other color options: Lilac Micro and Fades of Summer. I would like to know more about the naming process and the profession of "coming up with marketing-suitable names for colors", but a quick Google search didn't get me any further.
The Bella Tech has raglan sleeves according to the manufacturer's website. Internet research was more productive here: Raglan sleeves are named after Lord Raglan (1788-1855). He lost an arm in the Battle of Waterloo and from then on needed modified coats to better fit his new body shape. The seam that connects the raglan sleeve to the rest runs diagonally from the armpit to the neck, not vertically from the armpit to the shoulder.
