The images seem washed out compared to the vibrant colours of Oolite 1.90:

Oolite 1.91 image:

The js code (from my Hoopy Casino oxp) producing the image is:
if(this.$cwin == "luck")
{
mission.runScreen({title: "C R A P S", choicesKey: "hoopy_dice_yesno"}, this.choiceEvaluation);
setScreenBackground({ name: ("dice" + this.$dice + ".png"), height: 480 });
}
Any suggestions as to how I can adjust / correct the colour of images displayed in dev ver 1.91?
With the exception of the display screen colour all other colours and brightness look fine in 1.91. I have disabled other oxps such as BGS but makes no difference.
