The red dye scare occurred in the 1970s when studies suggested that certain red food dyes were linked to cancer. This led to concerns about the safety of food dyes and prompted changes in regulations and labeling requirements for food products.
Red dye can be made from a variety of sources, such as plant extracts like beets or insects like cochineal bugs. Synthetic red dyes are often derived from petroleum-based chemicals. Each source produces different shades of red dye depending on the specific compounds used in the process.
The dye used in M&M's is a combination of synthetic food dyes such as FD&C Red 40, FD&C Blue 1, FD&C Yellow 5, and FD&C Yellow 6. These dyes are approved by the FDA for use in food products.
Who says they do? "Best" in what way? What you consider important and what I consider important may be two very different things. The exact color I want may not be available in a vegetable dye, or vegetable dyes may not "take" on the polyester fabric I'm trying to dye. Vegetable dyes may fade too quickly to be of any use. The point is that it's silly to ask which is the "best" dye without also specifying what the criteria are. Cheapest? Most colorfast? Widest color range? Least toxic? There are situations where any of those might trump the others.
Fugitive dyes are natural dyes that fade and/or change color dramatically over a long period of time (usually many years). Some fugitive dyes fade away completely, while others change color, for example, a bright blue fugitive dye might fade to a light tan. They were mostly used to dye fabric before the invention of chemical dyes in the early 20th century. Bleeding of dye colors is the transfer of a dye in fabric to part of the same fabric or another fabric when the fabric is wet. This can occur with older fabrics, and even with cheaper modern fabrics. The mostly likely dye color to bleed is red (although other colors can bleed). Washing white/light colored clothes separately from darker, more deeply dyed clothes is a common way to to avoid having dye from a dark fabric bleeding into a light or white fabric.
To make orange dye, get 3 onions, and 5 coins for yellow dye. then get 3 redberries, and another five coins for red dye. go to the witch in draynor village and make the dyes, then mix the yellow and red dyes

Red dyes are often made of insects. Carmine red, cochineal red, or natural red 4 are all made from insects, usually powdered beetles. Vegetarian red dye uses other resources. Use caution when selecting vegetarian dyes. Some vegetarian dyes, such as Red 2 and Red 40 are petroleum or coal based, and not considered all that healthy by some groups. Look for dyes that are vegetable or fruit based. Beets and pomegranates are sometimes used to make healthier vegetarian versions of these dyes.
Yes and no. Red and Yellow dyes cause cancer in mice. Blue dye can heal spinal injuries.
Red dye can come from both natural and synthetic sources. Historically, natural red dyes were derived from insects, such as cochineal, which produces carminic acid, and from plants like madder root. Today, many red dyes are synthetic, created through chemical processes to ensure consistency and safety in food and textiles. Common synthetic red dyes include Red 40 (Allura Red), which is widely used in food products.
