Daltonic Contrast

Hi,

I´m trying to find an option y increase the brithness and contrast in obsidian and if posible find a daltonic version (with reduced visibility with myopic vision.

Is there anything to help in this way for us? Daltonic and myopic?

If you can, can you answer me with links to the options if it is posible? I´m starting in this and I´m going very very slow.
