I had saved it in my Documents folder. |
| Point to the shapes on the canvas | These are the 3 shapes we created in an earlier assignment. |
| Point to the color palette | Recall that we had learnt to change color using the color palette at the bottom of the interface. |
| Click on the Fill and Stroke | Now we will learn how to fill colors of various types using Fill and Stroke.
Let's go to Object menu, and click on the Fill and Stroke option from the drop down list. |
| Point to the Fill and Stroke dialog box | Notice that the Fill and Stroke dialog box has opened on the right side of the interface. |
| Point to the 3 tabs | There are 3 tabs in this dialog box: Fill, Stroke paint and Stroke style |
| Click on the rectangle and point to Fill and stroke dialog box | Now, we will click on the rectangle in the canvas area.
Observe that the options and icons in the Fill and stroke dialog box get enabled. |
| Point to the Fill tab | First, we will learn about the Fill tab. |
| Point to the 6 icons | Notice there are 6 icons under the Fill tab.
Let us learn what these icons do. |
| Point to the No paint icon | The first icon is called No paint.
It indicates that the object will not be filled with any color. |
| Click on the icon and point to the rectangle | Click on the icon and notice the change in the rectangle.
The color of the rectangle has been removed. <<PAUSE>> |
| Point to the Flat color icon | The next icon is Flat color. It helps to fill a solid color into an object. |
| Click on the icon and point to the rectangle | Click on the Flat color icon and observe the change of colour in the rectangle shape. |
| Point to the 5 modes of filling color | Under Flat color, notice that there are 5 sub-tabs. |
| Point to RGB tab | By default, RGB tab is selected. |
| Point to the RGB slider | Under RGB tab, there are 4 sliders.
The first 3 sliders indicates the intensity of Red, Green and Blue colours. |
| Move the sliders in left or right directions | We can change the color by moving these sliders in left or right directions.
Observe the color change in the rectangle as I do so. |
| Point to Alpha slider. | The fourth slider is the Alpha slider.
With this, we can increase or decrease the opacity level of the colour from opaque to fully transparent. |
| Pointing to the RGBA box | As I move these 4 sliders, observe that
|
| Move one/two sliders in left or right directions | Let me move the sliders once again so that you can observe this change. |
| Point to the value of colors | * We can change the color manually
|
| Change the color values of Red, green and blue | Let me change the value of Red to 100, Green to 50 and Blue to 150.
Notice the color of the rectangle has now changed to violet. |
| Point to the Alpha slider | I keep the Alpha level as 255 since I do not want to reduce the opacity level.
<<PAUSE>> |
| Point the HSL tab | The next tab is HSL and it stands for Hue, Saturation and Lightness respectively. |
| Adjust the Hue slider | We can use the Hue slider to get a base color.
I move the slider towards the left direction to get a base of green color |
| Adjust the Saturation slider | We can adjust the saturation of the base colour using the Saturation slider.
Observe the change in the saturation level by moving the slider in left or right directions. |
| Adjust the Lightness slider | The Lightness slider adjusts the lightness of the base color.
With this option one can vary the shade of the base colour
|
| Point to the Alpha slider | As before, the Alpha slider is used
|
| Point to each slider of CMYK | The next tab is CMYK which denotes Cyan, Magenta, Yellow and Black respectively. |
