The Field Picker in FileMaker 15 has the field name text very close in color to the background color. For those of us that are color blind, it makes it difficult to read the field names. If FileMaker 14 the field name text was much brighter in comparison and much easier to read.
The field type on the same row is brighter and is easily read.
I find that every time I use the field picker, I have to increase the brightness of my monitor a great deal. Which for general use makes the monitor to bright.
