Custom colours in grids


I love that custom colours can be selected by choosing the hex code or RGB values. This is especially great for the dashboard views with the graphs, titles, etc.

One problem though is that we do not have the same option in grids. There the standard colours are the only options. Is it possible to add this to grids, or perhaps a workaround by entering the hex codes via the Smartsheet API?

I understand this is not a major request/issue, but I would benefit tremendously from this.
