如何将Rebol中的按钮设置为红色？尝试代码后仍显灰色

Ah, I spot the problem with your code! Just appending the RGB value 100.0.0 after the button label doesn’t work because Rebol’s View dialect doesn’t automatically interpret that as a color parameter. You need to explicitly use the color keyword to tell the widget what you’re setting.

Here’s the corrected version of your code that will make the button red:

View [button "colored" color 100.0.0]

If you prefer more readable syntax, Rebol also supports predefined color words (like red) or hexadecimal color codes (like #ff0000), which work the same way:

# Using a predefined color word
View [button "colored" color red]

# Using a hexadecimal color code
View [button "colored" color #ff0000]

Bonus tip: If you want to adjust the text color to contrast better with the red background, you can add the text-color keyword too:

View [button "colored" color red text-color white]
