How to color fields based field value and Blank value

[UMDTERPS]

Hi! 😃

First Question - I'm having a little trouble with my XML that is trying to color a field based on value and blank value. I have a field called "Status" that has a date in this format "3/24/2020" and if it doesn't have a date, it's blank.  If the field has a date the field will be green, if the field is blank it will be colored grey.

My current XML is as follows:

<format type="color" field="Status">
<colorPalette type="expression">if (like(value,""),"#00b33c","#A9A9A9")</colorPalette>

The above XML half works, it colors in the fields with dates Green, but the fields that are blank it leaves white as normal and doesn't give the grey color. 

Any ideas how to solve this with simple XML?

Second Question - Is it possible to color a specific cell a color using simple XML?

Are they blank (present with nothing in) or null (not present). Try something like

<format type="color" field="Status">
<colorPalette type="expression">if (isnotnull(value),"#A9A9A9","#00b33c")</colorPalette>

Looks like if you flip the color scheme it works:

<colorPalette type="expression">if (isnotnull(value),"#00b33c","#A9A9A9")</colorPalette>
