Colors in Color Schems appear wrong.

[manngo]

Description of the problem or steps to reproduce

I’m trying to concoct my own color scheme. I’m basing it on the Simple theme. I’m new to Micro, so maybe I’m misunderstanding something.

If I use the color “white”, either by name or by hex code (#ffffff), it appears as grey. Yellow comes out more like olive. Etc.

It appears that the colours are much darker than expected.

I have attached an image:

This is likely an issue with your terminal and/or how it is configured. If your terminal is only using 16 or 256 colors (which is often the default behavior unless the COLORTERM environment variable is set to "truecolor" even in terminals that support true color) it will just pick the "closest" one to the color you wanted.

You can find more information about how colors work in terminals and how to check if your terminal supports true color: https://github.com/termstandard/colors

OK, I think I have worked this out. It turns out that there were two issues.

First, there is the question of colour names. Apparently, white doesn’t mean “white”. It means grey. The same goes for the other colours. Using the “bright” version of the colour names is usually closer to the true meaning of the colour, but not always. I have managed to adjust my terminal settings, but I’m aware that the ANSI standard doesn’t match my expectation. More on this here:

The alternative is to work purely in hex values. To make this more reliable, we need to tell Micro that we’re using true colour. I’ve add this in my .bashrc file:

export COLORTERM=truecolor
export MICRO_TRUECOLOR=1
