Thanks @scarf005

After seeing the screenshots, I think the current problem is in the colors. This is how I see the build log in my computer (macos):

The page url is white and the source file is gray, so it makes easy to distinguish them.

But in your terminal, the colors are not applied. Do you have any configuration for that? Can you try if other colors are visible?

[scarf005]

I'm using konsole, and turns out dim isn't supported.

[oscarotero]

Okay, so I propose to modify the dim format in Lume and use gray instead.
And also remove the bold style because it's not needed.
What do you think?

[scarf005]

sounds good, should we also take account for bright themes?

[oscarotero]

If it's possible to detect dark/light themes it would be great.
But I guess gray will work fine in both themes.

Thank you!

er, wait, i think this hasn't been properly removed:

lume/core/writer.ts

Lines 146 to 149 in e4a98be

	log.info(fmt({
	from: entry.flags.has("remote") ? entry.src : entry.path,
	to: file.outputPath,
	}));
