![]() I have a sample reference of what the HCY'(601) color picker will look like:Īlso, just in case, here's the PSD file of that image, along with my macro-enabled excel spreadsheet that I did to do the HCY' calcs.DISCLOSURE: This post may contain affiliate links, which means when you click a link and make a purchase, we receive a commission.Ĭalling all Potterheads and makeup lovers! Have you been dying to try out all those popular eyeshadow looks you see on TikTok and Instagram, but can’t find inspiration? Get ready to have the best makeup at Hogwarts! Since you are implementing the traditional color picker soon, I figured out it's the time to do the HCY' colorspace check there. (forgot to mention, x = Hue angle from 0 to 360) I already mentioned the calc on how to do the chroma correction, however, I do think I haven't mentioned how I calculated "Pure Chroma Value" Although this can be passed as what Bob Ross will say "Happy Little Accidents", the hues and especially the lumas will not be accurate at all. This tends to happen on the HCY' colorspace if you just do the raw calculation without chroma corrections, as stated in the previous post. Just look at the Lightness slider on this pic for example transitioning to a brownish red to yellow: What I have noticed is the colors for the specific hues are not matching, especially on high chroma areas. Okay, some feedback from HCY', especially now that you are implementing traditional color pickers. This will be great as it's typically good to have both a HSV/HCY' colorspace for actual colorpicking adjustments and Lab for temperature adjustments. What coolorus did was to allow me to have access to all colorspace sliders they have. A minor request, if its possible, can you make the UI for the color sliders to be similar to what coolorus has? This is pretty important especially for painters as your typical HSV/HSL colorspaces do not take account of the actual local values of the colors itself (HSL is even worse as the S value is normalized and L value assumes pure saturated colors have the same local value as 50% gray).ģ. Primarily speaking, the goal for both of this painting wise is to separate the "value" (being light to dark) to the actual color. Lab/HCL has taken account perceptual stuff on the colorspace that push it differently as HCY' Will request for the same reason as the HCY' colorspace. Lab sliders and HCL colorspace (a cylindrical transfom of Lab): Frank Reilly's students for example has books that teach painting with extended use of the Munsell colorspace and it will be great to apply the same theories in digital.ī. ![]() If it's possible to edit the Y' coefficients in settings, that will be a great bonus.Īnother great thing about it is, it acts as a bootleg Munsell colorspace that traditional painters used. Take note that I used Y'601 instead of Y'709 for the same photoshop reason. This is a pretty important colorspace IMO as these are the values that's used on Photoshop Blending Modes (Hue, Saturation, Color and Luminosity). ![]() Just like HSV, HCY' is calculated using RGB with following formula: ![]() It will look like the lower right picker of this picture: ![]() Can I request some colorspace features? I would primarily ask for:Ī. What colorspace does the "RGBs" colorpicker used? what logic does it use to determine where each color is located?Ģ. ![]()
