Colour saturation help

Hi Herbert,

I´ve been trying with the option of color saturation of some visualization (diverging option), but it does not satisfy my expectations, so when I saw your answer to this matter, decided i need to try it your way. 

My report acctually has 5 different fields/tables (Leading, Managing, Onboarding, PAC, Whitebelt) each one for a specific thema.

In each Table i created a measure named KPI. For each KPI i have a specific target. Would like to give them a conditional color using your formula. If target is reach should be green, if -10% below of the target yellow, if its even lower red.

So i figured out i need to create a new table with each KPI name and the target. 

KPI's                        Target              Color

Leading                     90%

Managing                 90%

Onboarding              100%  

PAC                          90%

Whitebelt                 90%

My question is, how I should write your color formula, if each KPI comes from a measure of a different table. Should be something like this? How should I do the part of -10% of target = Yellow, -20% or less of target= red???

Color = IF ( NewTable[KPI´s] >= TableLeading[LeadingKPI]

                                                    TableManaging[ManagingKPI]

                                                    TableOnboarding[OnboardingKPI]

                                                    TablePAC[PACKPI]

                                                    TableWhitebelt[WhitebeltKPI],

¨Green¨, ¨Yellow¨, ¨Red¨) 

Would appreciate your input on this.

Thanks!
