<div dir="ltr">Hi Jon,<div><br></div><div>You should note that NCL is a zero-index language. This means that your colors are indexed 0-253 for that table, as BlueYellowRed contains 256 colors as a color map and 254 as a color palette.</div>
<div><br></div><div><a href="http://www.ncl.ucar.edu/Document/Graphics/ColorTables/BlueYellowRed.shtml">http://www.ncl.ucar.edu/Document/Graphics/ColorTables/BlueYellowRed.shtml</a><br></div><div><br></div><div>Without looking at your code, it looks like you're trying to explicitly reference a 255th color, which simply doesn't exist. There are a few ways to manage this if you need a full 255 colors. The most common is probably cnSpanFillPalette, which I'm pretty sure will duplicate colors at points within the spectrum to create the extra colors if the count of your levels exceeds the count of your colors. It's generally used for making a plot with fewer plot levels than there are colors, however. If you are looking to do something else with the colors, I can give you some more complicated FillColor management suggestions as well that I tend to use in most of my plots.</div>
