How to use custom links?

Hey! Added package as 

```
(use-package org-special-block-extras
  :straight t
  :ensure t
  :after org)

``` 

Added to txt file with org mode:
```
[[color:red][thsis is red text]]

[[color:#ff0066][pinkish text]]

[[red:][hey]]

[[red:This will appear red]]

```
Switched on org-special-block-extras-mode. Links are collapsed, but i can see no any color.
