Abstract painting gave Frost a greater freedom to invent, to draw on his emotional response
 to the observed scene rather than to depict it literally

'Black and Green Borders' painted in 1957; what makes this painting so special is that it was painted during Frost's brief period in Yorkshire. Whereas in Cornwall he felt like a giant in that landscape, and this is reflected in his work for a large part ion his life, during this brief period in Leeds he had the opposite response to the landscape around him.

'...going out to Otley and Ilkley Moor and places like that you suddenly become minute in walking in this vast landscape which comes up to place like Girdle Scar... I mean there they are, standing up right in front of you and you are just nothing, you're like a pin head. And that made difference to me, and I think helped me to flatten up, to bring the canvas up much closer and flatter... I didn't stand back and look at it, came right up to it, because that's what I did in the landscape in Yorkshire
