Chapter 1 An Overview of the Shake User Interface 77

Click the plus (+) sign to the left of the Color control to access color subparameters. The

first row in the subtree contains a slider to modify one channel at a time. Select the

button that corresponds to the desired channel: (R)ed, (G)reen, (B)lue, (O)ffset, (H)ue,

(S)aturation, (V)alue, (T)emperature, (M)agenta-Cyan, or (L)uminance. Move the slider

to calculate according to the selected channel, but convert the numbers back to RGB.

Edit the individual channels or add expressions in the subtree.

You can also keep the subtree closed, and use the Color control (the color swatch) itself

as a virtual slider. Using the channel buttons as the keyboard guide, press and hold the

desired key (R, G, B, H, S, V, and so on) and drag left or right in the Color control. In the

following illustration, when G is pressed and the pointer is dragged, the green channel

increases or decreases.

Note: To adjust the red, green, and blue color channels at the same time, press O and

drag in the Color control (O represents Offset).

Using Pop-Up Menus

Some parameters have associated pop-up menus, such as the font parameter in the

Text node.

There are two ways to choose items from a pop-up menu:

Click a menu item to choose that item, then close the menu.

Right-click a menu item to choose it and remain in the menu. When you first click the

menu item, hold down the left mouse button and move the pointer off of the menu.

Then return the pointer to the menu and right-click. This allows you to quickly test

different parameters.
