Put a container field behind everything else on your layout.
Insert or paste a rectangle of the desired color into this container field. (use "expand or contract" date formatting option to ensure rectangle perfectly fills the container field.)
Depending on what you need, you can either put this field in a related record and use the relationship to specify the record with the desired color or you can use a container field with global storage. Either way, you can put this field on many different layouts and changing the color in the field (or using the relationship to refer to a different record) will change the background color in all of your layouts where you use the container field for this purpose.
Thanks for the ideas. I tried both and was not sure if I did either correctly.
In the end, I have copied a block of colour into a container. I selected reduce or enlarge to fit in inspector. I assume this is not best as if I want to use the colour for a large area of a layout I imagine the quality will degrade as I am using an image of a colour.
Can I tile the square of colour. Phil I think that is what you were suggesting but I do not see how to do that. I will look into that further.
Thank you for your valuble assistance.
Actually, you are doing exactly what I suggested. For a single color background, this should work. We used to use containers like this for conditional effects all the time before we had conditional formatting.
The key is in what you want to do next. You can set up a table of records with your container field so that each record stores a different color. You can then set up a relationshp so that you can manipulate the relationshp to link to a different records in order to display different background colors.
You can also make this a global field loaded via script so that one field can be used for background color on all layouts regardless of the underlying table associated with it.
I understand. Thanks for the help. I have set up as you say and am using a the relationship for manipulate the container for different used.
