How to change colors.

There are 2 ways:

1.In the tile editor, stand on that certain tile, doubleclick it and from there, you should see the rest. Colors are at the bottom, drawing tablet at the middle.

2.Quest=>Graphics=>Sprites. Choose here that certain sprite, click on its image and change the CSet with +- keyboard keys.

Addition!
You can edit the palettes. With it, you change the color of all (or almost all) of the sprites, combos. Go to Quest=>Graphics=>Palettes. Changing the Main Palette changes a lot of things. The non-leveldependant CSets (5,6,7,8,10,11) only can be changed by this way. In the Level Palettes section you can add a new palette without changing others. Sometimes you want to hange only a few things, like adding an overworld CSet into a dungeon palette. This way you can put greenies (grass, flowers, trees) into a dungeon quite simply.
But palette editing is for those whos at least a little experienced.

Thanks! 😃

But, um... How do I get to the tile editor?:shrug:

Off the top of my head I believe it's Quest -> Graphics -> Tiles.

Thanks. 😊
