When you apply strikethrough or underline to text in Illustrator you can't define the color or weight of that line. Is there an easy way to do this? Maybe using an effect and saving that as a style?
- Add a new fill via the Appearance Panel
- Set the Fill color to the color you want your strikethrough/underline
- Highlight this new fill in the Appearance Panel
Effect > Convert To Shape > Rectanglefrom the menu
- Tick the Absolute option and enter the height and width you want the rule/line
Effect > Distort & Transform > Transformto move the rule/line to some other position on the text
Remember, when you're done doing this once, you can drag the text to the Graphic Styles panel. That way, in the future, you simply need to click the style to apply your custom strikethrough/underline.
(How it was done before Adobe added the underline/strikethrough options to Illustrator.)
