Nematode Body Structure. The phrase tube-within-a-tube is a convenient way to think of nematode body structure, and also a term used to refer to a major trend in the evolution of triploblastic metazoa (Brusca and Brusca, 1990 Invertebrates).
Neutrals and Universal Colors. Let me explain in details... In general, neutrals include black, white, gray (mix black with white and you've got gray) and different shades of brown. Nowadays a color can be called a neutral based on how effectively it can blend in with other colors. Basically, they match with all colors and color combinations - and don't create much of an emotion.
1 White, black, and grey are neutral colors (and are very important for properly coordinating clothing). 2  When a color is tinted that means that it's getting lighter (has white added to it) and when it is a shade it is getting darker (has black added to it). 3  Tones in a color are created by adding grey.atterns can be really hard to coordinate, so you'll want to make sure that you don't overdo it with your patterns or you don't overshadow the pattern with the rest of your outfit. 1  Try doing 1 pattern with 1 or 2 plain neutrals. 2  You could also try putting 1 pattern with 1 plain color from within the pattern.
