What do you think is theme to the poem Fragmentary Blue by Robert Frost?

Why make so much of fragmentary blue


In here and there a bird, or butterfly,


Or flower, or wearing-stone, or open eye,


When heaven presents in sheets the solid hue?


Since earth is earth, perhaps, not heaven (as yet)--


Though some savants make earth include the sky;


And blue so far above us comes so high,


It only gives our wish for blue a whet.





Need help trying to understand what the theme would be to this poem.

it plays with color blue of sky and blue of gloom. why worry about this less divinely inspired earth!
