In answer to your question, let me say that Lord Visnu is served by Sesa who is also an incarnation of Visnu. His business is to supply all bodily comforts to Lord Visnu. Sesa, or Ananta, serves Visnu as His Mattress and protects Him from all atmospheric disturbances by making His heads like a canopy or umbrella. In this way, He supplies umbrella, bedding, slippers, and everything else personally required by Lord Visnu. This information we get from scriptural sources. So keeping pace with this scriptural injunction, you may paint nicely as Krishna gives you instruction.
