Blend and merge both combine things into one, with a difference in texture. Blend is to mix things into a smooth, uniform whole in which the parts can no longer be told apart. Merge is for separate things to combine into a single whole, one absorbed into the other. Both lose the separate parts; blend stresses a seamless mixture, merge a joining of two into one.
Both end with one thing where there were several, but they picture it differently. Blend mixes things until they are a smooth, even whole — two colours become a new colour with no seam anywhere. Merge, from mergere 'to plunge', has two things combine so that one runs on where there were two — often larger, countable bodies like lanes or firms. You blend the paint; two lanes merge. One is an even mixture; the other a joining of two into one.
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.
merge
To merge is for two separate things to come together into one — lanes of traffic merge, companies merge, datasets merge. From the Latin mergere 'to plunge or dip', it once meant to sink in, and still carries that sense of one thing taken into another until they are no longer separate. When two firms merge they form a single company; where two rivers merge, one name usually wins. To merge is a broader, often deliberate move than to coalesce, and a close relative of consolidate.

Both lose the separate parts, so listen for texture and scale. Blend makes a smooth, even whole — blue and yellow gone, only green, uniform throughout. Merge joins two into one — two lanes becoming a single line, often of larger, countable things. If the result is a seamless mixture, that is blend; if two bodies combine so one runs on, that is merge.

Blend stresses a smooth, uniform mixture, often of substances or qualities; merge stresses two things joining into one, often larger bodies. Both lose the separate parts, but you blend flavours and colours, while you merge lanes, files and firms. Blend also means to fit in unnoticed, a sense merge lacks.
