What color represents honesty and truth?
Blue. Blue is one of the most common colors brands choose because it's the most trustworthy. It communicates wisdom, freedom, loyalty, and honesty.
Over all contexts and Web sites, the blue color scheme was perceived as most trustworthy and the black color scheme as least trustworthy.
According to Conroy, the primary association of the color blue for most of recorded history was with truth a meaning that leaves a remnant in our language in the phrase "true blue." This was because blue is the color of a calm and clear sky, and it is in calm reflection that leads to truth.
White is the symbol of truth, unadulterated by dishonesty. White can be blinding to those accustomed to the dark, and it can illuminate the literal and figurative ills of society. White is the ideal foil ā the contrast against which all other colors look more vibrant.
A dot (Universal) A dot is a modern symbol that is used to represent the truth. It is simple yet so effective. A dot is honestāit is what it is and it doesn't hide anything or try to be something that it is not.
Blue: Cool blue is perceived as trustworthy, dependable, fiscally responsible and secure. Strongly associated with the sky and sea, blue is serene and universally well-liked. Blue is an especially popular color with financial institutions, as its message of stability inspires trust.
Primary Colors: The primary colors are red, yellow, and blue. These colors are considered pure because they cannot be made from any other colors.
The color purple is often associated with royalty, nobility, luxury, power, and ambition. Purple also represents meanings of wealth, extravagance, creativity, wisdom, dignity, grandeur, devotion, peace, pride, mystery, independence, and magic.
Purple. Purple makes you feel creative. Purple is associated with mystery, creativity, royalty and wealth. Lighter shades of purple are often used to soothe or calm a viewer, hence why it is used in beauty products.
Grey Color Meaning
In color psychology, grey represents neutrality and balance. Its color meaning likely comes from being the shade between white and black. However, grey does carry some negative connotations, particularly when it comes to depression and loss.
Why is gray the color of truth?
For, to the French, gray is the colour of truth, ideality, and life itself. Their devotion to form and ordonnance, rather than to colour and romantic effects, is gray, and hence an intellectual trait.
The color blue represents both the sky and the sea and is associated with open spaces, freedom, intuition, imagination, inspiration, and sensitivity. Blue also represents meanings of depth, trust, loyalty, sincerity, wisdom, confidence, stability, faith, and intelligence.

Because it's associated with optimism and energy, many brands use orange to convey a message of positivity. If you're looking to get your audience excited about something, go for orange. It's an attention-grabbing, warm color that really pops when combined with cool blue or green tones.
Daffodil (Narcissus)
Daffodils symbolize honesty and truth.
I would suggest a simple dot: . It is inscrutable, symbolic of something deep inside: Hence TRUTH. It is honest: it does not hide anything: it is not drawn on something else.
The Hawk is one of the most valiant birds that proudly represents courage, self-awareness, truth, and perspective.

It is also the color associated with intelligence (doctorate in black robe; black horn rimmed glasses, etc.)
1. BLUE. Blue is the most loved color by humans being preferred by more than 35% of world's population which basically means that every 4 people in a group of ten favor blue over any other color which is kinda surprising because blue also happens to be the rarest occurring natural color.
