Blend and join both bring things together, with a difference in what happens to the parts. Blend is to mix things into a smooth, uniform whole in which the parts can no longer be told apart. Join is to connect two things directly, or to become a member of a group. Blend dissolves the parts into one; join links them while they stay distinct.
Both bring things together, but blend erases the parts and join keeps them. Blend mixes separate things until no seam is left — two colours make a third. Join, from Latin jungere 'to yoke', connects two things directly — two pipes, two hands — or adds a person to a group, with the parts still plainly themselves. You blend blue and yellow into green; you join two lengths of chain. One melts the parts into one; the other links them while they remain distinct.
blend
To blend is to mix things so thoroughly that they form one smooth, even whole with no visible join — flavours blend, colours blend, voices blend into harmony. From the Old Norse blanda, 'to mix'. Unlike things that merely combine and stay distinct, what blends loses its separate edge; and to blend in is to match your surroundings so closely you go unnoticed. A blend is also the noun for the result you can merge from parts kept in set proportions: a coffee blend, a blend of styles.
join
To join is to connect two things directly, or to become part of a group — join two pipes end to end, join a club, join hands. From the Latin iungere, 'to yoke'. At its simplest it makes one continuous thing out of two: where two roads meet, they can be joined into a single route. With people it means to enter or take up with — you join a team, join the queue, join forces. Unlike things that merge into one body, joined parts keep their own ends; they are linked, not dissolved.

Ask whether the parts vanish or stay linked. Blend dissolves them into one uniform whole — the blue and yellow gone, only green left. Join keeps them distinct and connects them at a point — a fresh link closing two chains into one run. If the parts merge into one indistinguishable thing, that is blend; if they are linked while staying themselves, that is join.

Blend erases the parts into one uniform whole; join links things that stay plainly distinct, and covers membership (join a club) as well as connection (join two wires). 'Blend in' means to disappear into a group, while to join a group is to become a visible member of it — near-opposite social pictures despite both being about coming together.
A clear register and meaning pair. Join is the everyday, all-purpose verb — join two parts, join a group, forces join — where the parts stay distinct. Blend suits things mixing into a uniform whole ('blend the ingredients', 'a blend of styles') and, figuratively, fitting in unnoticed. Examiners reward the fit: join for linking or membership, a blend for a seamless mixture. Note the grammar — you join one thing to another, and the noun is a join or a joint, whereas blend gives a blend.
