That does simple compared to mine, but if anyone is wodering here is how i do it:
• thinking of the theme(planing). As a starter you gotta looked at the theme, finding theme like what art do you want to show with this palette, why do ypu want go use this pallete, and etc
• colour circle-ing. After thinking of the theme, i always start of from a alpha colour which is a colour that i start with, i then change the hsb of the colour multiple times as i want, when im done i go to the next step
•colour grouping. This step is showned as it is, grouping colour like a ramp as usual, this step is mainly to a universal type of palette theme
• colour eleminations. At this step you maybe want to remove some of colours with near brightness point due that sometimes its not very cohesive or even you want to reached your colours limit, the easy way to find what colour is not good just grayscale the pallete and see what colour has the almost near brightness but dont remove it if has the opposite side of the hue and cohesive on its own group. Upon elemitating colours and find a drastic ramp on some of the colour group, repeat only step 2 but use the nearby colours.

And there you have it, my way of choosing colours hope anyone find this somewhat usefull
