At last! Now all the color selection features are done except text input - and each part interacts with the other! Pressing the + sign for red, for example, will change the other slider gradients to include the new red value, display the numerical value, and move each slider - on top of incrementing the value by one.

Very nice GUI, great job.

Nice! You're making much more progress than I am with the personal MML maker I planned to make for myself. I look foward to seeing how this goes. Keep up the good work.
