Changing the color and transparency of an instance
Each instance of a symbol can have its own color effect. To set color and transparency options for
instances, you use the Property inspector. Settings in the Property inspector also affect bitmaps
placed within symbols.
When you change the color and transparency for an instance in a specific frame, Flash makes the
change as soon as it displays that frame. To make gradual color changes, you must apply a motion
tween. When tweening color, you enter different effect settings in starting and ending keyframes
of an instance, and then tween the settings to make the instance's colors shift over time. See
"Tweening instances, groups, and type" on page
Note: If you apply a color effect to a movie clip symbol that has multiple frames, Flash applies the
effect to every frame in the movie clip symbol.
To change the color and transparency of an instance:
Select the instance on the Stage and select Window > Properties.
1.
In the Property inspector, select one of the following options from the Color pop-up menu:
2.
Brightness
adjusts the relative lightness or darkness of the image, measured on a scale from
black (–100%) to white (100%). Click the triangle and drag the slider or enter a value in the
text box to adjust brightness.
Tint colors the instance with the same hue. Use the Tint slider in the Property inspector to set
the tint percentage, from transparent (0%) to completely saturated (100%). Click the triangle
and drag the slider or enter a value in the text box to adjust tint. To select a color, enter red,
green, and blue values in the respective text boxes, or click the color box and select a color from
the pop-up window or click the Color Picker button.
Alpha adjusts the transparency of the instance, from transparent (0%) to completely
saturated (100%). To adjust the alpha value, click the triangle and drag the slider or enter a
value in the text box.
Advanced
separately adjusts the red, green, blue, and transparency values of an instance. This
is most useful when you want to create and animate subtle color effects on objects such as
bitmaps. The controls on the left let you reduce the color or transparency values by a specified
percentage. The controls on the right let you reduce or increase the color or transparency
values by a constant value.
The current red, green, blue, and alpha values are multiplied by the percentage values, and
then added to the constant values in the right column, producing the new color values. For
example, if the current red value is 100, setting the left slider to 50% and the right slider to
100 produces a new red value of 150 ([100 x .5] + 100 = 150).
Note: The Advanced settings in the Effect panel implement the function (a * y+ b)= x where a is the
percentage specified in the left set of text boxes, y is the color of the original bitmap, b is the value
specified in the right set of text boxes, and x is the resulting effect (between 0 and 255 for RGB,
and 0 and 100 for alpha transparency).
You can also change the color of an instance using the ActionScript Color object. For detailed
information on the Color object, see "Color class" in Flash ActionScript Language Reference
