For near white colors, your intermediate values (e.g. `sepiared`) can exceed 255.
255 (0xFF) is the maximum value that can fit in an `unsigned char`

18,296,394 | I've got a list of instances of a particular class Foo, that has a field bar:

I'd like to "convert" this to just a list of bar items, so that I have `bar[1..n]`
Sorry for the 1..n notation - I'm just trying to indicate I have an arbitrarily long list.

```
bar = [ i.bar for i in foo ]
```
Also, list indices in python start from 0, so a list of N elements would have items from `0` to `n - 1`. | >

How in the heck is that a list? A list looks like this:
```
[1, 2, 3]
```
How does `foo[1..n].bar` fit that format? Like this?
```
foo[1, 2, 3].bar

That's nonsensical.
