Even after the recent update ce(contrast) still isn't selecting the most contrasting colour between white and black. I've worked around the problem by implementing a formula based on w3 guidelines (https://www.w3.org/TR/WCAG20/#contrast-ratiodef) to calculate it manually, now I adapted that into sudo java code (not a java programmer). Would be really glad to see this implemented. (there might be a mistake in the second function, I didn't test this)

```
// this assumes Color is a type exposing GetR(), GetG() and GetB()
// implemented https://www.w3.org/TR/WCAG20/#relativeluminancedef
double GetLuminance(Color c) {
double rsRGB = c.GetR() / (double)255;
double gsRGB = c.GetG() / (double)255;
double bsRGB = c.GetB() / (double)255;
double r, g, b;
if(rsRGB <= 0.03928)
r = rsRGB/12.92;
else
r = Math.pow((rsRGB + 0.055)/1.055, 2.4);
if(gsRGB <= 0.03928)
g = gsRGB/12.92;
else
g = Math.pow((gsRGB + 0.055)/1.055, 2.4);
if(bsRGB <= 0.03928)
b = bsRGB/12.92;
else
b = Math.pow((bsRGB + 0.055)/1.055, 2.4);
return 0.2126 * r + 0.7152 * g + 0.0722 * bl
}
Color GetBlackOrWhiteForBestContrast(Color c) {
if(GetLuminance(Color.Black) + 0.5 / GetLuminance(c) + 0.05 > GetLuminance(Color.White) + 0.5 / GetLuminance(c) + 0.05)
return Color.Black;
else
return Color.White;
}
```
