Colour the World Yellow

It's been quite a long time since I posted anything, and indeed since I've coherently expressed myself in a non-technical format (well, I wonder if this counts, given its lack of coherency). Here goes to creaking rusty joints, in the name of my recent loss of self-expression:

Whilst the sky bleeds blue's true hue,
  Could I colour the world yellow?
Would the pigments blend softly
  and slew into dearth earthen, fallow.

Joyful regret, smiling hides nothing, but colours few;
  lost in shades,
Wouldst the lonely figments meeting, cohere?
  Memory evades...

When black and white flow white and black,
  Could flowers bloom but grey?
With hollow stares,
  we change tack till justice, fears allay.
