I bought this thread specifically for red but what I got was not red at all. I would call it a shade of orange from Home Depot, and the yellow is actually a light pumpkin orange. I like blue and green colors but they also look weird. They are a sort of pastel color, both lighter than true blue or true green. Although I can't use it for its intended purpose, I'm still glad I bought it. I am very impressed with the quality and am sure I will use all four colors over time. My general conclusion is that this is a great suggestion if you need different thread colors for printing on desktop toys. The filament has excellent adhesion and quality (better than my Hatchbox PLA) and it's a great deal for the price. However, if you need red, yellow, green, or blue thread for a project, this pack is not for you. The colors are just kind of off, which is hard to explain. Also, they are translucent, not solid. I placed them between the red and orange hatchbox thread so you can see where they are on the color scale :)
