# Colorblind settings

> Every Refined - Graphics setting on the Colorblind tab: what it does, its unit, range and default.

These are the rows on the **Colorblind** tab of **Options > Refined - Graphics**. The game's own options on the same tab are not listed here.

## Colorblind Mode

| Setting | What it does | Range and unit | Default |
| - | - | - | - |
| **Colorblind Mode**<br />`color_vision.enabled` | Shifts the colors you cannot tell apart into ones you can, for red-weak, green-weak, blue-weak or no color vision. The HUD keeps its own colors. Never brighter than the game's picture. | On or off | Off |
| **Colorblind Type**<br />`color_vision.type_choice` | Which colors are hard to tell apart. Deuteranomaly (Green-Weak) is the most common, then Protanomaly (Red-Weak); Tritanomaly (Blue-Weak) confuses blues and yellows; Achromatopsia (No Color) sees only brightness. Each also covers the stronger form (deuteranopia, protanopia, tritanopia). | One of `deutan`, `protan`, `tritan`, `achromat` | `deutan` |
| **Filter Mode**<br />`color_vision.mode_choice` | Correct changes the colors for you to play with. Simulate shows how the game looks with this color vision; Check Correction shows how the corrected picture looks with it, to test the settings with normal color vision. | One of `correct`, `simulate`, `check` | `correct` |
| **Severity**<br />`color_vision.severity_share` | How strong the color weakness is. The highest is a missing cone type (dichromacy), or no color vision at all with No Color. | 0.1 to 1<br />a share, 0 none and 1 all | `0.6` |
| **Correction Strength**<br />`color_vision.correction_share` | How far the colors you cannot tell apart are shifted into ones you can. Has no effect with No Color, where Lightness Cues does the work. | 0 to 1<br />a share, 0 none and 1 all | `1` |
| **Lightness Cues**<br />`color_vision.lightness_share` | Darkens the colors you would mix up with their partner, reds for red and green weakness, blues for blue weakness, so they differ in brightness too. Never brightens anything. | 0 to 1<br />a share, 0 none and 1 all | `0.3` |
| **Preview Split**<br />`color_vision.split_choice` | Changes only the left half of the screen, with a line down the middle, to compare with the game's own colors on the right. | One of `whole`, `left_half` | `whole` |
