Customizing gradient shading

[mcgonma]

Is there a way to customize gradient shading? I have a column of 97 rows that I want to show a gradient from dark to light, but I don't want it to be an even spread from top to bottom the way the functionality of "Format Cells" does. For example, if you're familiar with the Gradient function of Shape Fill in PowerPoint, you can have several stops and adjust the amount of shading from one end to the other.
Is this at all possible?
(P.S. - before you suggest that I just color the cells progressively from one color down to another....I'm colorblind so I can't do that).

I'm familiar with the type of gradient you're asking for but I don't think you can do what you want in Excel. I still think there is a way with one colour that you could vary progressively in spite of saying don't suggest that. After all, the gradient is basically a variation of shades on one colour, right? However, it would require that you use code (macro). If this is across columns in a row, then the column count would have to be known for the entire range and also the number of columns in each range within that would be shaded differently. I've never done this but believe it's doable. Not sure what would be the best way to approach the inputs but maybe a userform. It's a non-starter if you're in a corporate environment that will not permit vba code (wb has to be xlsm type).
