Translation:Now the artist wants to increase the amount of colors.
Yeah usually we would put the "now" at the end. The way it is currently puts the emphasis is on NOW. As if you had suggested to the artist that they should add more colours but they ignored you. Then further down the line (perhaps when it is awkward to do so) they finally change their mind "NOW the artist wants to add more colours! That will be so much more work for me!".
