Value describes the "the lightness of the colour, by the given S". It doesn't matter how hard we try, we can't get more saturated colour. According to the same resoning as above, we'd have to clip any value greater than 1 to 1. Similarly we can't have any colour saturated more than for the S value of 1. In other words, I'd suggest clipping all negative values to 0. So, if our colour can't be any less saturated, then values less than 0 are meaningless-we hit our bottom with 0, period. What if we've had saturation less than 0? "0" means the lowest saturation perceivable-effectively, colour is one of the shades of gray (regardless of the hue).
Generally, add modulo 360 before storing the output value and forget about it }. So if we've got, say, value of "-25", then it's the same as if we've had H equal to "360-25", that is "335". What does it mean if H value is less than 0? It means that we "rotated our hue past 0 degrees". H values are cyclical (like values of sin or cos functions).
Its value is between 0 and 360 degrees (containing 0, excluding 360, because 360 degrees can be understood as "0 degrees again"). Let's try to think one component at a time and what are the consequences of crossing its allowed range. There are many possible ways to deal with the situation at hand. HsvOutput.V = hsvDestination.V + hsvMemory.V HsvOutput.S = hsvDestination.S + hsvMemory.S HsvOutput.H = hsvDestination.H + thsvMemory.H Creating hsvOutput by applying Differences to hsvDestination HsvMemory.V = hsvSimilarColor.V - hsvMainColor.V HsvMemory.S = hsvSimilarColor.S - hsvMainColor.S HsvMemory.H = hsvSimilarColor.H - hsvMainColor.H So my question, if an H(0>n>360) S,V(0>n>1) gets beneath or above its value-area, how do i need to change it (and do I also need to change the other two values) for getting the right value?
#Negative color converter archive
Similar colors to rgb1 will be changed to the related color, by saving the HSV-difference between hsv1 and hsv2 and aplying these to every similar color.ĭoing this in HSV was verry helpfull, since in RGB I wasn't able to archive this, but now i get errors, because sometimes an HSV-Value gets negative. In my c#-application, I use an RGB to HSV (and back) converter for changing a specified color-spectrum to another.
