如何使用单元格的应用程序脚本将 Google 表格数据验证添加到列中，以仅允许输入颜色和十六进制颜色代码

Question

see image of spreadsheet here example: Google sheet cells may only allow "brown", "red", "green" etc. and hex color codes to be inputted eg #03fca9. How would one go about this using apps script for an entire column? Any help would be greatly appreciated!

You can use Apps Script for validation but you don't have to. Highlight the target range, select 'Data validation' -> 'Custom formula is' and input the formula below:

=REGEXMATCH(A1,"([#0-9a-fA-F]){6}|green|red|blue|purple")

The validation will be based on whether the formula evaluates to TRUE. I'm not an expert in REGEX so there might be better options to write this expression. For example, my expression will not reject whitespaces, etc. The downside is that you'll have to list all colour aliases manually. Also, the expression only tests user input against the pattern - there's no way to check if the input is a valid colour.

In code, you can do the same by calling this method of the DataValidationBuilder class to build a rule and apply it to the range

var range = SpreadsheetApp.getActive().getRange('A1:A');
var rule = SpreadsheetApp.newDataValidation().requireFormulaSatisfied('=REGEXMATCH(A1,"([#0-9a-fA-F]){6}|green|red|blue|purple")').build();
range.setDataValidation(rule);
