Ok, or I'm just thinking entirely wrong or I'm never going to get through here.
Here being the prince's room with the 3 chairs, i got the sphere thign and put it in the chair and now I think I have 3 colours that make a short melody, am I looking too much behind this? Or should I sing that melody, cause I've tried several combinations but I don't think i hit the right one and I don't know because I'm colourblind.
Please help. -_-;
