    Perfect colors!
  • u/tzador
    Almost, if only we had a few more bytes..
  • u/rodrigo.siqueira
    Can you paste in the comments the larger version (with your color idea)? Maybe there are ways to save a few more bytes.. e.g.instead of 430+(9*i*j/30+i*13)-5*j you can use 500+i*j/3+i*9-j*5 (6 bytes smaller) or even 300+i*j/3+i*9 (10 bytes smaller)
  • u/rodrigo.siqueira
    And you also save 4 bytes by using 9*j+360+h directly inside x.fillRect (instead of defining y=9*j+360+h and then using y)
  • u/rodrigo.siqueira
    And also x.fillStyle=R() instead of x.fillStyle='#000'
