The slide technique noted above works, as does just stretching your pinky over to hit Orange. Depending on the song and what's coming up I alternate between the two. For chords I'll usually stretch, during solo passages I'll slide my hand.
To get an idea of what would be best for you, I'd suggest trying the songs in Practice Mode. Slow them down, see what you find easier and go from there.
They're games people, just enjoy them! You could be stuck at work!
