Changing brightness When you choose Brightness from the Color drop-down list, a slider and a text box appear. Type a brightness percentage or drag the slider and see the result immediately in the symbol instance. High brightness makes the image light, and 100-percent brightness makes the instance disappear. Low brightness makes the image dark so that 0-percent brightness turns the instance black. Changing tint When you choose Tint from the Color drop-down list, you can pick the color and then the amount of the color (the tint), by percentage, that you want to apply. Figure 7-5 shows the controls for this option. You can pick a color by clicking the Tint Color button and choosing from the color swatches or type red, green, and blue values (if you know them). Specify the percentage of the color that you want to apply by typing a value in the percent text box or by clicking the drop-down arrow and dragging the slider to choose a percentage. When the percentage is set to 100%, the instance completely changes to the color that you specified. If the percentage is set to 0%, Flash leaves the instance unchanged. The Flash method of specifying a color gives you great flexibility and precision. You can choose a color and use the tint control to create a meld of the current color and your chosen color. If you want to stick to the 216 Web-safe color palette, just select a color swatch from the ones displayed when you click the Tint Color button and then slide the tint control all the way up to 100%. Changing transparency Choose Alpha from the Color Effect drop-down menu to change the transparency of an instance. (Alpha enables levels of transparency, and you can think of the term as somewhat synonymous to opaqueness.) Use the slider or type a value in the text box. A value of 0 means that your instance becomes completely transparent in that case, when you return to the Stage, all you Figure 7-5: Changing color and tint used on a symbol instance. 158 Part III: Getting Symbolic
