The test
Could you, or your colonoscopist, see through this and spot a tiny lesion on the bowel wall? If the answer is no, it is not clear enough. Colour charts are not a substitute for that.

What is a clear fluid?
A clear fluid is a translucent liquid with no solid bits. Juice must be pulp-free, not freshly juiced or blended.
If in doubt: could I, or my colonoscopist, see through this and spot a tiny lesion on the bowel wall?
See-through, and nothing to chew
The hours your clinic names as clear fluids are not a second white diet. They are the part of prep where the view has to stay clear. Hold the glass to the light. If you cannot see through it, it is not a clear fluid.
Pulp, seeds, herbs, cream, and anything you blended until it looked smooth still count as solids. Freshly juiced and blended are not the same as pulp-free from a bottle.
This is generic advice and does not override any specific instructions from your doctor or clinic. Your sheet names the hours, and what you may drink in them.
Within 6 hours
Within 6 hours of anaesthetic or sedation: no jelly, gelatin, or egg white. A whiskey-sour mocktail is a nice idea. It is still egg white.
Sheets do not agree
Clinics disagree on colour, cola, alcohol, orange juice, and when jelly is allowed. This page will not publish a national list of those. Use the test, then follow the sheet you were given.
Clear-fluid recipes from the book
The Colonoscopy Cookbook includes five clear-fluid recipes by Sophie Hansen. Two you can see already: roasted vegetable broth, and fresh orange jellies. They are still recipes for the window your clinic allows, not a reason to ignore a ban on that sheet.
If jelly is on your sheet as allowed, stop it within 6 hours of anaesthetic or sedation. If your sheet bans jelly altogether, leave it out.
