@uhafner, ECharts API says that [color](https://echarts.apache.org/en/option.html#color) could be defined by a **string** in three formats: 'rgb(255,0,0)', '#ff0000' or 'red'. So when you use ```color: "oklch(50% 0.2155 150deg)"``` ECharts considers it an invalid **string** and ignores it. I do not know if or when _oklch_ color format will be supported in ECharts. I made an effort in my Demo above to search, adapt, test and share a conversion **function** _ok2rgb_. It uses the **absolute** value syntax of _oklch_ to convert LCH values to color format 'rgb()' The [relative value syntax](https://developer.mozilla.org/en-US/docs/Web/CSS/color_value/oklch) you are using ```oklch(from oklch(...)...)``` is not supported. But you are welcome to enhance _ok2rgb_ and make it work with relative syntax as well. And if you are successful, please share. -- This is an automated message from the Apache Git Service.
