Pronunciation: [mˈə͡ʊvɪblˌuː] (IPA) 
Mauveblue is an interesting word because of its spelling. In IPA phonetic transcription, it can be written as /mɔːvbluː/. The word combines the colors mauve and blue, with the first three letters of mauve being combined with the word blue. This gives the word an unusual spelling that can be difficult to remember or pronounce. However, it is a unique and creative way to describe a color that is a mixture of purple and blue.
There doesn't appear to be an official etymology for the word "mauveblue" since it seems to be a made-up term. However, it can be inferred that "mauve" and "blue" are combined to describe a color that is a blend of the two shades.
"Mauve" comes from the French word "mauve", which means "mallow" (a type of flower). The color mauve is a pale purple or pinkish-lilac shade. It gained popularity in the late 19th century.
"Blue" is derived from the Old English word "blǣwen", which originally referred to a dark color similar to black. Over time, the meaning of "blue" shifted to describe the color we now associate with the sky or water.
