The red eft (juvenile) stage is a bright orangish-red, with darker red spots outlined in black. An eastern newt can have as many as 21 of these spots. The pattern of these spots differs among the subspecies. An eastern newt's time to get from larva to eft is about three months.
A terrestrial subadult Eastern newt or red eft, Notophthalmus viridescens. Salamanders of the family Salamandridae with aquatic adult stages are called newts. Some newts, including the Eastern newt, have a juvenile terrestrial stage called the eft. The red eft has aposematic coloring to warn predators of its toxic skin.

Yellow, orange, and red are the colors generally used, often with black for greater contrast. Sometimes, the animal postures if attacked, revealing a flash of warning hue on its underside. The red eft, the brightly colored terrestrial juvenile form of the eastern newt (Notophthalmus viridescens), is highly poisonous.
A 1908 color wheel with red, green, and violet "plus colors" and magenta, yellow, and cyan blue "minus colors". The typical artists' paint or pigment color wheel includes the blue, red, and yellow primary colors. The corresponding secondary colors are green, orange, and violet or purple.
Pitohuis, red and black birds whose toxic feathers and skin apparently comes from the poisonous beetles they ingest, could be included. [17] It has been proposed that aposematism played a role in human evolution, body odour carrying a warning to predators of large hominins able to defend themselves with weapons.
Birds selectively avoid to predate all-red or erythristic color P. cinereus because they think that red color is a signal of noxiousness and toxicity. Even if people trained the birds to enhance the avoidance by increasing exposure to red efts (juvenile Notophthalmus viridescens), the frequencies of erythrism is never above 25%. [25]
