Spiders can be any color some spiders are blended with other colors, some might have a design on their back
It depends what type of spider. Some are brown, black, red, green, I've even seen orange spiders!!! there are also blue and yellow spiders
The spiders blood is blue.
spiders have black and white vision, so they don't have any favorites or dislikes
Spiders are all colors (and they change color when the moult to camouflage themselves better!)
Spiders have blue blood. In human blood oxygen is bound to hemoglobin which contains iron, giving it the blood a red color. In spiders, as well as other Arthropods and Molluscs, oxygen is bound to hemocyanin which contains copper, giving its blood a blue color. The same interaction that causes oxygenated blood to color, also causes iron rust to appear reddish and the oxidized copper to appear green. However, I have noticed no color in spider blood before.
All spiders are poisonous; some venoms just have no or little discernible effect on humans. Color is not necessarily an indication of toxicity. Some spiders are red to blend in with their surroundings, some are red as a warning, and really are venomous, and some a red to mimic the truly venomous ones. In any case, color alone is not enough to determine how poisonous a spider is.

Not usually. Markings can differ between male and female spiders of the same species, however male spiders are not usually lighter in color. They are typically smaller than female spiders though.
The female wolf spiders carry their egg sacs which are attached to their abdomens. These egg sacs appear blueish in color.
Wolf spiders can get pretty big, as well as orb weavers.
Spiders have circulatory systems just as humans do. However, their blood is colorless blood and is called hemolymph. It transports nutrients, hormones, oxygen and cells.
