so I have something like...

canvasItems = [
        { 
            Text:"This is ImageCanvas 1"
            TextAttrs:{Color:"#FFFFFFFF", Font:"Medium",
            HAlign:"HCenter", VAlign:"VCenter",
            Direction:"LeftToRight"}
            TargetRect:{x:390,y:357,w:500,h:60}
        },
        { 
            Text:"This is ImageCanvas 2"
            TextAttrs:{Color:"#FFFFFFFF", Font:"Medium",
            HAlign:"HCenter", VAlign:"VCenter",
            Direction:"LeftToRight"}
            TargetRect:{x:390,y:357,w:500,h:60}
        },
        { 
            Text:"This is ImageCanvas 3"
            TextAttrs:{Color:"#FFFFFFFF", Font:"Medium",
            HAlign:"HCenter", VAlign:"VCenter",
            Direction:"LeftToRight"}
            TargetRect:{x:390,y:357,w:500,h:60}
        }
    ] 

I've previously been changing the text color by a roByteArray conversion

								
fadelevel = CreateObject("roByteArray")
fadelevel.fromhexstring(device.nextoverlayfontcolor)
fadelevel[0] = fadelevel[0] - 8   ' or whatever values.									
canvasitems = [
            Text:"This is ImageCanvas 3"
            TextAttrs:{Color:"#" + fadelevel.tohexstring(), Font:"Medium",
            HAlign:"HCenter", VAlign:"VCenter",
            Direction:"LeftToRight"}
            TargetRect:{x:390,y:357,w:500,h:60}
		]
canvas.SetLayer(0, {Color:"#FF000000", CompositionMode:"Source"}) 
canvas.SetLayer(1, canvasItems)
   canvas.Show() 

And that worked fine for one canvas Item. My question is how do I roll thru an array of canvas items and change a value in all the TextAttrs nested Arrays?

If you just want to change the TextAttrs element you don't need to redefine all the other elements. You should be able to do something like this.

for each item in canvasitems
    item.TextAttrs.Color = "#" + fadelevel.tohexstring()
end for

simple enough!
