Crayon Maestro is a full-fledged wax crayon simulator lets you create art, whether a complete drawing or just a sketch, with a striking resemblance to its real life counterpart.
₁ Since version 4 (the code was completely rewritten).
All the control knobs in the toolbar can be changed and adjusted while you draw, by using the number keys (1, 2, 3...) on your keyboard.
The Mac’s full screen mode is supported. You can remove the toolbar if you place the pointer on it and scroll toward the screen/window edge, or if you press the Tab key on your keyboard. To get it back, scroll inward from near the edge. You can also move the toolbar to the other side by scrolling it in that direction, or by pressing Shift-Tab.
On a trackpad, you can pinch to zoom, and use the rotation gesture to rotate the picture. Scroll over the picture to pan. On the keyboard, use the Arrow keys (pan) and - + buttons (zoom). Use the Space key or the smart zoom gesture to reset zoom, pan, and rotation. Again to go back.
Everything from selecting a layer to adding new ones can be done in the Layer Control. To open the Layer Control, click the button that has a mountain/house/flower (symbolizing the selected layer).
You can also change the color of the paper beneath the layer(s), by clicking “Paper Color”.
There’s a scrollable palette, where you can pick colors, as well as store new ones. To edit any palette section, right-click on a color in it, and a menu will appear.
Adjacent to the palette are three control knobs that adjust the hue, saturation, and brightness of the current color. Note that you can adjust the color while you draw!
The Current Color button is the large colored rectangle next to the knobs. Clicking this button brings up a menu with some options, including “Eyedropper”.
