I like [Steve Purcell's SanityInc Tomorrow themes](https://github.com/purcell/color-theme-sanityinc-tomorrow), but would like something between `night` and `bright`.
I copied `emacs/.local/elpa/color-theme-sanityinc-tomorrow-20220412.1643/sanityinc-tomorrow-night-theme.el` and `./emacs/.local/elpa/color-theme-sanityinc-tomorrow-20220412.1643/color-theme-sanityinc-tomorrow.el` to `~/.config/doom/themes` and added `my-` to each. I then added a color definition I called `dusk` to `my-color-theme-sanityinc-tomorrow.el`:
```

< '((night . ((background . "#1d1f21")
---
> '((dusk . ((background . "#1d1f21")
> (alt-background . "#151515151515")
> (current-line . "#2a2a2a")
> (selection . "#424242")

> (defun color-theme-sanityinc-tomorrow-dusk ()
> "Apply the tomorrow dusk theme."

```
And created this `my-sanityinc-tomorrow-dusk-theme.el`:
```
(add-load-path! "/Users/aqjo/.config/doom/themes")
(require 'my-color-theme-sanityinc-tomorrow)
(color-theme-sanityinc-tomorrow-dusk)
```
Despite my having defined it as shown above, the latest error I'm getting is `Symbol's function definition is void: color-theme-sanityinc-tomorrow-dusk`.
I feel like I might be making this more difficult than it needs to be. Is there a simple way to define a theme with the colors I want without all the intricacies that are in this set of themes?
In fact, I might use `afternoon` or `dark+` if I could make the alt-background (I think it is) more prominent.
Thanks
